A1SiN Oxidation Resistance Measurement With 3D Profilometry

Oxidation resistance is critical for metal components in high temperature environments. Exposure to high temperatures can result in the depletion of the metal with rapid oxidation and material loss. Without protective coatings, surface oxidation adversely affects the performance and durability of the metal component. For example, engine parts, turbine blades, tooling and many others. It will be critical to measure with profilometer the protective coating chosen for a given application.
