Abstract

Abstract: The Al2 O3 –40%TiO2 (AT40) coating doped with the different contents of Yttria-stabilized zirconia (YSZ) on mild steel prepared by plasma spraying was studied. The different compositions of the YSZ powders are varied by 8 wt% and 20 wt%. The coating with 20 wt% YSZ exhibits a smaller wear rate and better hardness property than that with 8 wt% YSZ, which could be found through the wear resistance and Vickers hardness tests. The YSZ addition promotes the formation of Al0.1 Zr0.9 O1.95 and then increases the wear and hardness properties of the composite ceramic coating.
