Micro Materials collaboration with GP Plasma and SIOMEC

Residual stresses in coated components can influence their performance. Micro Materials have been collaborating with GP Plasma and SIOMEC to study residual stress profiles in thin hard coatings.

By performing a grid of indentations within a calotte crater with the NanoTest Vantage and analysing the results with the unique SIO software, it was possible to produce a detailed map of the through-thickness stress profile in the studied PECVD coating. The results showed higher tensile stress at the interface, implying a weakened interface likely to suffer adhesion problems in service.
