In this paper, Al2O3/TiO2 coatings via thermal spray approach using three different feedstock powders, i.e., (a) reconstituted nanosized Al2O3/TiO2 feedstock powders, (b) reconstituted nanosized Al2O3/TiO2/ZrO2/CeO2 feedstock powders and (c) conventional Al2O3/TiO2 feedstock powders are described. Effects of different powder types and various plasma spray conditions on the density, microhardness and crack resistance, especially on the abrasive wear behavior of the coatings have been evaluated. The result showed that the coatings sprayed using different feedstock powders exhibit different abrasive wear behavior with changing the plasma spray conditions. The coatings sprayed using the reconstituted nanosized Al2O3/TiO2/ZrO2/CeO2 feedstock powders showed a significantly improved wear resistance compared to the coatings sprayed using reconstituted nanosized Al2O3/TiO2 feedstock powders or conventional Al2O3/TiO2 feedstock powders. The wear mechanisms of the coatings were discussed.
