Understanding Coating Failure Using Scratch Testing

The process of scratching is carried out in a controlled and monitored manner to observe adhesive or cohesive failures. In this study, different coatings were tested and compared using Nanovea Mechanical Tester to showcase the capacity of the instrument and investigate the behaviors of different coatings during the scratch testing.

In-Situ Wear Measurement At High Temperature Using Tribometer

Wear measurement of alumina silicate ceramic is simulated at high temperature in a controlled and monitored manner using the Nanovea Tribometer. In this study, we would like to showcase the capacity of the Tribometer for in-situ monitoring the evolution of the wear process of materials at elevated temperatures.

Transparent Film on Transparent Substrate Measurement

The Nanovea PS50 Profilometer is used for roughness measurement, step height thickness and optical thickness of a thin transparent film on a transparent glass substrate. Step height will be obtained by measuring an area of the film and an area where the substrate is exposed for relative height difference, while optical thickness will be measured by using the Profilometer capability of measuring through the transparent film and detecting a reflecting both from the top surface of the film and the substrate simultaneously.
