A1SiN Oxidation Resistance Measurement With 3D Profilometry

Submitted by NANOVEA on Thu, 02/16/2012 - 03:40

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.

Shot Peened Surface Characterization Using 3D Profilometry

Shot peening is a process by which a substrate is impacted with round metal, glass or ceramic beads, also known as shot, at a force intended to create plasticity on the surface. The characteristics present prior to and after the peening process provides vital information to better the understanding and control of the process. Among many others, surface roughness and dimple coverage area left by the shot, are of particular interest using a profilometer.
