The first and most enduring application of nanoindentation is the characterization of hard coatings designed for mechanical and chemical protection of an underlying material. Diamond-like carbon is a common coating of this kind, with typical coating thickness being less than 100nm. This session is a live demonstration of nanoindentation with the KLA iNano, optimized for very shallow nanoinden...

Although optical coatings are designed for the control of light (anti-reflective, reflective, splitting, filtering, etc.) it is their mechanical properties which govern longevity. Scratches at any scale lead to excessive absorption of laser energy causing localized thermal stress and ultimate failure. This session is a live demonstration of dynamic nanoindentation with the KLA iMicro nanoindent...

Knowledge of Young’s modulus is essential for the design and control of the extensive fractures required for harvesting natural gas from shale formations. Nanoindentation of drill fragments provides an economical and localized way to measure Young’s modulus of shale. This session is a live demonstration of standardized nanoindentation with the KLA iMicro nanoindenter to characterize shale. Ms. ...

In its most basic form, instrumented indentation involves pressing an indenter of known geometry into a test surface while continuously monitoring force and displacement. In this session, we review the test and analysis commonly known as the “Oliver-Pharr” method for measuring hardness and Young’s modulus. The continuous measurement of force and displacement affords two important advantages ove...

The first and most enduring application of nanoindentation is the characterization of hard coatings designed for mechanical and chemical protection of an underlying material. This session is a live demonstration of standardized nanoindentation with the KLA iMicro nanoindenter to characterize an industrial nitride coating on a tungsten- carbide substrate. Ms. Hay demonstrates sample mounting, in...
