How to deal with roughness in nanoindentation measurements

Nanoindentation is often used for hardness measurements of thin films and coatings. For nano-range samples, a low indentation depth is required to obtain accurate hardness and elastic modulus without the influence of the substrate. However, the surface roughness of many coatings and thin films can negatively affect the results, leading to a large variability in the data.

In this webinar Anton Paar scientists will show the effects of roughness on the hardness results on ceramic coatings and on bulk metallic materials. 
Additionally, methods for reducing the variation in hardness testing results, without compromising the data quality, will be discussed. 

Join the free webinar to find out more about the methods used for decreasing the variation of results of the nanoindentation measurements!

Jiří Nohava, PhD.

Jiri Nohava is the Head of Product Competence & Lead Application Scientist of the Mechanical Surface Characterization unit at Anton Paar. He obtained his PhD in materials science at the Czech Technical University in Prague. He joined Anton Paar in 2007 and has become a specialist in instrumented indentation and tribology in various domains. His main task is development of new applications with Anton Paar instruments in scientific and industrial projects. He regularly publishes in peer-reviewed journals and participates in international conferences.

Mark Haase, PhD.

Mark Haase completed his PhD studies in Chemical Engineering at the University of Cincinnati, on the synthesis and characterization of Spinnable Carbon Nanotube Arrays. Prior to that, Mark earned a Master of Science and Bachelor of Science degree in Chemical Engineering from the Illinois Institute of Technology. During his academic career, Mark extensively used AFMs and other characterization tools, which benefited him starting his new career as Commercial Application Scientist at Anton Paar USA in 2018. Mark has been supporting researchers and engineers in academic and corporate environments solving materials testing challenges ever since.
