Influence of Deposition Parameters on Adhesion/Cohesion of Plasma Sprayed TiO2 Coatings

Abstract:

Article Preview

Adhesion/cohesion is one of the most important properties for coatings. It is related with their durability and functionality of coatings. In this study, a series of TiO2 coatings were prepared by atmosphere plasma spraying under different deposition parameters. Their adhesion or cohesion was evaluated as a function of coating thickness as well as deposition parameters using the scratch test. In addition, the influence of deposition parameters on coating porosity, surface roughness, and microhardness is discussed. The results indicate that the deposition parameters investigated have a remarkable influence on coating porosity and microhardness as well as adhesion or cohesion, but no obvious influence was observed for surface roughness.
