Abstract

In this study, the surface of aluminum alloy was coated with and without bond coat with Cr2O3/Al2O3 powders by using plasma spray technique. The coating layers were examined with optical microscopy, SEM, EDS and XRD analysis. The microhardness of specimens was measured. In XRD studies, such compounds as α-Cr2O3, Cr2O3 and Al2O3 have been identified on coating layers. The maximum hardness value has been determined in the sample coated with Cr2O3..
