New: True coating's E modulus and hardness for only €100

The new O&PfC Light (Oliver&Pharr for Coatings) is on sale now for only 100 €.
The new O&PfC Light (Oliver&Pharr for Coatings) is on sale now for only 100 €.
April 1, 2015

Rather than 3000 €, the new O&PfC Light for physical analysis of instrumented indentations is only 100 € (excl. VAT) now! Nevertheless it can determine the true elastic modulus, hardness, and yield strength of a coating.

No April Fools' joke: The new version 2.0 of O&PfC Light is on sale for only 100 € (excl. VAT) instead of formerly 3000 €! Because it focuses now strictly on the essentials with respect to physical analysis of indentation measurements helping beginners to get started: determination of elastic modulus, hardness, and yield strength of the coating taking the substrate effect into account.

The best thing about it is that physical material properties like Young's modulus and yield strength can be used for simulation-driven design or optimization of surface structures for any intended use - e.g. by means of FilmDoctor which is based on the same analytic model and thus much quicker and easier-to-use than Finite Element Models.

New: comparable tribology experiments thanks to physical designing of experiments

The software Test Optimizer for automatic designing of experiments. New: also for tribo experiments now!
The software Test Optimizer for automatic designing of experiments. New: also for tribo experiments now!
March 30, 2015

The software Test Optimizer for automatic designing of experimens has been extended to tribology experiments in order to get comparable and meaningful results from different tribology experiments.

A physical design of experiments is an essential requirement in order to obtain significant and comparable results (e.g. elastic modulus, yield strength, hardness, tensile strength, shear strength, adhesion, etc.) of surfaces by means of contact experiments like indentation or scratch test. To that effect the software Test Optimizer has been developed which allows an automatic designing of experiments in just a few minutes.

This Test Optimizer has been extended to tribology experiments like pin-on-disc or calotte grinding test now allowing one to obtain not only significant but also comparable results from different tribology experiments. This Test Optimizer is on sale 50% off for only 1000 € (excl. VAT) until end of 2015.

Why will we not be at the ICMCTF 2015?

Test Optimizer Webservice is now online available.
Test Optimizer Webservice is now online available.
March 27, 2015

An unpleasant incident led to us deciding not to go to the ICMCTF 2015 in San Diego.

How come? You will learn here.

Initially, we wanted to release a worldwide novelty at the ICMCTF this year. However, you don't have to go without it! That is to say, we just release it now: the Test Optimizer Webservice. Because you can use it instantly online and don't have to go to San Diego.

This webservice allows you to design your indentations, scratch tests, calotte grinding tests, and tribology tests online in a few minutes in order that your experiments will result in significant and comparable results. And all that from as little as 1 € (excl. VAT) and no software installation is necessary!

August 28, 2014

You know solar eclipse. Of course. But have you heard of shadow effects in surface mechanics (particularly indentation/scratch testing)? Nick Bierwisch explains it at the ThGOT 2014, Leipzig, Sep 4.

Shadow effects and surface mechanics - what's the point? Light doesn't play a role there. Admittedly, it's to be rethought somewhat, because we have applied the term to stresses. We thought laterally again. Sorry! However, this effect is crucial as soon as the surface is not homogeneous anymore. And you will be able to follow Nick Bierwisch's talk smoothly if you understood how solar eclipse works (what we strongly suppose):

This talks is part of the 4th Optics Colloquium which is taking place in conjunction with the 10th ThGOT, September 2-4, Leipzig.

Ultra-hard nanotwinned diamond

July 8, 2014

Comment on unprecedented hardness results (up to 203 GPa) of nanotwinned diamond recently published in Nature.

Recently, the paper “Nanotwinned diamond with unprecedented hardness and stability” by Quan Huang et al. has been published in the renowned journal Nature. The authors claim to have measured ultra-hardness values of up to 203 GPa for their nanotwinned diamond by Vickers indentation measurements without any observable damage of the indenter tip - which was made of regular diamond. Therefore, we have written a critical comment to this paper pointing out a few contradictions in this work.

A Rockwell hardness test HRC is not suited for coatings at all
November 19, 2013

A free video tutorial shows how contact experiments like indentation tests or scratch tests can be designed quickly for coatings or treated surfaces by means of the free trial edition of the software Test Optimizer.

The first part of this free video tutorial shows why it is important to properly design contact experiments (e.g. hardness tests, indentation tests, scratch tests) for coatings or similar surface structures. A Rockwell hardness test HRC as well as a scratch test according to DIN EN 1071 on a 20 µm TiN coating will be analyzed for this purpose.

The second part of this tutorial demonstrates how such mechanical surface tests can easily be dimensioned for thin films by means of the software Test Optimizer. A free 14-days trial edition of Test Optimizer is also available now, so you can try it yourself.

Special Offer: Time-dependent E modulus by O&PfC now 90% off

Evolving von Mises stress profile during hold period of indentation measurement on visco-elastic PBC.
Evolving von Mises stress profile during hold period of indentation measurement on visco-elastic PBC.
October 21, 2013

O&PfC Light NG incl. Creep module at 90% off until end of year. It enables one to compute time-dependent elastic modulus of materials with significant creep.

When analysing instrumented indentation tests (e.g. nanoindentation, micro hardness test, etc.) on surfaces or samples with significant time-dependent material behavior (creep: exponent often m>2 of the fit function) the time-dependent Young's modulus E(t) can now be calculated by our functional prototype O&PfC Light NG. This is not only important with respect to polymers, tissues or similar materials, but also with respect to surfaces or coatings which are exposed to elevated temperatures in its application as they are closer to their melting point.

This functional prototype can compute the true time-dependent elastic modulus as well as storage modulus E' and loss modulus E'' of the coating on the basis of the hold part of conventional load-depth curves. In addition, a new test procedure has been introduced enabling a numerically more stable determination of the time-dependent elastic modulus on the basis of several unloading curves with different strain rates. This approach assumes the whole sample as homogeneous half space for now. It will be extended to the actual sample structure subsequently during the test period and provided to active prototype testers (minimum: one bug report) for free.

This special O&PfC Light NG prototype will be on sale onetime at 90% off while stocks last.

Some of the result pages of Test Optimizer showing properly dimensioned nanoindentation measurements and scratch tests in 2D and 3D
August 6, 2013

Computer-aided dimensioning of indentation measuremens and scratch tests for coated surfaces is now child's play with the new Test Optimizer and can be done quickly before the experiment.

A proper design of experiment is the key to a successful, namely significant, experiment. A vital component of such design is an appropriate dimensioning of the measurement with respect to mechanical surface tests: maximum normal load, type of indenter tip or stylus, radius or tip rounding, minimum distance between measurement positions, and minimum number of measurements are the most important parameters regarding indentation measurements and scratch tests which must fit in order to obtain utilizable information about the coating or its adhesion.

Now these parameters can be calculated automatically by Test Optimizer allowing you to dimension your experiment within 1 minute on an up-to-date computer!

Try Test Optimizer Light 14 days for free now! Those days of shots in the dark or time-consuming and costly trial-and-error testing are gone. In addition, Test Optimizer Light is now on sale 50% off while stocks last!

The Ultra-Hardness Delusion

April 18, 2013

Final results of Dr. Schwarzers first-principles paper regarding the theoretically possible hardness of those allegedly ultra-hard nanocomposite coatings published.

In order to close the chapter of nanocomposite coatings which Stan Veprek still claims to be ultra-hard despite the lack of any proof, Norbert Schwarzer has calculated their theoretically possible hardness applying the energy approach following Marcus Fuchs' suggestion. The result of his paper "Is Ultra-Hardness Possible - A Brief Feasibility Study - Extended Edition" published in SIO's open access online archive is quite disillusioning:
the theoretically possible hardness of Veprek's nc-TiN/a-Si3N4/a-TiS2 coatings calculated from first principles is less than 40 GPa. This complements the attempts to properly calculate the hardness based on the little available data by Fischer-Cripps et al. and Fuchs, because it was not possible to take all effects on the measurement appropriately into account.

Another result of this study are parameter ranges in which super- or ultra-hard nanocomposite coatings are theoretically possible. Answering these two questions was encouraged by Marcus Fuchs in order to put an end to the ultra-hardness myth.

Result details can be found in the paper as well as on our focused topic page.

WOM 2013 - 19th International Conference on Wear of Materials
WOM 2013 - 19th International Conference on Wear of Materials
April 4, 2013

About a forgotten manuscript, an exemplary review and why we still think that WOM-participants should learn about a comprehensive new method on the identification of generic tribological parameters and subsequent surface optimization.

The 19th International Conference on Wear of Materials is approaching and even though it was not our intention to play only an outside role, we, that is to say the Saxonian Institute of Surface Mechanics will, unfortunately, not be participating. Why? This question will be covered on our focused topic page "Endlessly Touchable".

Based on the general editor's valuable comments Dr. Schwarzer revised his paper "Endlessly Touchable - the Next Generation of Surface and Coating Optimization" and decided to publish it in the online archive of SIO instead. Another advantage of this option is the unlimited free access as it is an Open Access archive.

The influence of deposited surface structures on mechanical properties

April 24, 2012

Marcus Fuchs' new presentation on "The influence of deposited surface structures on mechanical properties" is online

Abstract:

It is well known and logical that certain deposition parameters have a great effect on surface structures like surface roughness, interface roughness, porosity, intergrain interaction, homogeneity or grain size. However, it is almost impossible to find deposition parameters or even ranges of them for processing of specific surface structures which are generally valid for all deposition techniques as there is a broad variety of them. Even with the same deposition technique only slight changes in the geometry of the deposition configuration can cause big differences. But such surface structures can influence the apparent mechanical properties of surface materials due to the method which is usually applied for determining them. Preferably one uses contact experiments like load-displacement sensing indentation measurements with subsequent classic Oliver & Pharr analysis, scratch or highly sophisticated (physicalized1) tribological tests. Consequently, deposition parameters can effect the resulting mechanical material properties like yield strength Y, hardness H and elastic modulus E. Such effects should be taken into account during the parameter identification analyzes of mechanical material properties. Because they are not only important for quantification of the mechanical behavior of coatings, but also important indicators (e.g. H in relation to E) for the tribological performance (e.g. wear, friction) of tribological coatings. Nevertheless, it is not possible to derive such effects on the mechanical material properties solely from the deposition parameters as a result of the dynamic nature of any deposition process. Hence, it is very important to know the resulting coating structure of a deposition process. It should be measured after processing when the surface is in a static state. Such effects and their partially dramatic influence on the resulting mechanical properties will be demonstrated on the examples of ta-C and nano-composite coatings. For example it will be shown how simple roughness can lead to false apparent ultra-hardness results. In the same context it is demonstrated how inadequate or incomplete analyzes features and theoretical approaches can directly lead to severely flawed conclusion about the actual coatings stability and reliability. Last but not least, of course, it will be shown how it is been done correctly.

CSM User Meeting 2010

October 22, 2010

Dr. Schwarzer is going to give a talk on 27 October at 12 o'clock

On this year's CSM User Meeting in Chexbres, Switzerland, Dr. Norbert Schwarzer is going to give a talk about "Physical scratch test".

Attention: The program committee has changed the program! The talk will be on Wednesday, 27 October 2010, at 12 o'clock.

What exactly is a classical scratch test with respect to its physical meaning?

Only by answering this question sufficient correctly we can be sure to model and analyze a scratch test such a way, that meaningful generic parameters can be extracted. Thus, first of all a scratch test is a multiaxial contact test not only coming with normal and lateral loads, but also with tilting and twisting moments. While local normal and lateral loads are measured directly with most scratch test devices, the consideration of tilting and twisting moments requires somewhat more sophisticated means. A so called pre-scan with a near-zero load or even a complete surface scan (e.g. with an AFM) is necessary in order to obtain the surface structure before the scratch. This surface structure or geometry information (roughness) will later help to evaluate the local loading conditions at each position of the indenter in an highly accurate manner. In addition information about the amount of plastic deformation is required. Here a post-scan can help. But great care is necessary with its interpretation in case the scratch tip itself has been used for this measurement step, because not always does the scan depth present the maximum residual depth. This is simply due to the fact, that lateral inaccuracy, bluntness of the probe and smallest particles laying in the scratch trench compromising the residual depth result. A way out of this can be a proper combination of the scratch test with nanoindentation and highly sophisticated modeling. With such a comprehensive measurement approach also temperature effects and even rather complex structural information and failure mechanisms can be evaluated, discussed and used for later material optimization procedures.

Plenary lecture at ThGOT

May 8, 2010

Dr. Schwarzer gives plenary talk at 6th ThGOT on 8 September 2010

Based on the latest theoretical knowledge in mechanical loading of treated surfaces not only better modeling and simulation possibilities have been created, but also entirely new test methods were suggested. Theses tests should be developed in the framework of two new Europe-wide projects in order to extract new standards. The major objectives are, on the one hand, enhancing accuracy and reliability of experimantal results and, on the other hand, particularly evaluation of real and sustainable physical parameters. Instead of " stands up" or "fails" statements real quality and lifetime predictions should be facilitated. Therefore, better tailoring of tests to intended applications as well as using models perfectly adapted to experiments is necessary. These models enable one not only to obtain physical parameters from complex surface measurements, but also to extrapolate to intended applications.

Dr. Norbert Schwarzer talks about current state of this work and its advantages for practice in his plenary lecture "Next generation of multi-axial mechanical surface measurements and better modeling possibilities" on 8 September 2010 at 08:30am at the 6th ThGOT in Gera, Germany.
