Indentation University Webinar Session 21: How to Scratch TiAlN on WC
The first and most enduring application of nanoindentation is the characterization of hard coatings designed for mechanical and chemical protection of an underlying material. Quantitative scratch testing with a nanoindenter provides a convenient way to characterize the adhesion of such coatings. This session is a live demonstration. Mrs. Hay demonstrates all aspects of scratch testing a TiAlN coating, including sample preparation, instrument configuration, test specification, and interpretation of results. Critical load under two different test conditions (scratch velocity) are compared for significant difference using the student-t test.
