Microstructures and wear properties of YPSZ/CeO2 reinforced composites deposited by laser cladding

In this study, the influence of YPSZ/CeO2 on the surface performance of the laser-cladded composites was firstly researched. Laser cladding of the Fe3Al/Co42B + YPSZ/CeO2 pre-placed powders on Ti–6Al–4V alloy can form the composite coating, which increased the wear resistance of the substrate. With addition of 20 wt.%TiC, the longevity of the molten pool decreased, leading to the decreasing of the growth time of the precipitates and the content of CoTi, TiNi, AlNi, Ti3Al and TiB phases. The addition of 20 wt.%TiC did not improve the tribological properties of the Fe3Al/Co42B + YPSZ/CeO2 laser-cladded composite coating.
