Notes:
Wear resistance of Al2O3-8wt.%TiO2 coatings plasma-sprayed using nanopowders wasinvestigated. Four types of nanostructured Al2O3-8wt.%TiO2 powders were plasma-sprayed on alow-carbon steel substrate by using different critical plasma spray parameters (CPSP). The coatingsconsisted of completely melted and partially melted regions. The hardness of the coatings increasedwith increasing CPSP, while the wear resistance was the highest for the coating sprayed with thelowest CPSP. The main wear mechanism was a delamination mode in the coating sprayed with thehigh CPSP, but was changed to an abrasive mode in the coating sprayed with the low CPSP.According to this change in the wear mechanism, the wear resistance was the best in the coatingsprayed with lowest CPSP, while its hardness was lowest
