Plasma Spray Coating of an AA 2024-T4 Al Alloy with Oxide Powders

Abstract

In this study, the surface of AA2024-T4 Al alloy substrate was coated by Al(2)O(3) + TiO(2) powders without and with NiAl bond coat by using a plasma spray process. The TiO2 content was added at different concentrations (3, 13 and 40 wt.-%) to the Al(2)O(
