摘要：

Tungsten boride (WB) powder was used as a wear-resistance material, then clad on a Ti-6Al-4V substrate by the gas tungsten arc welding (GTAW) method. The titanium boride (TiB) reinforcing phase was formed in situ in the clad layer during the cladding process. Since the TiB and tungsten (W) reinforcing phase exist in the clad layer, the hardness of the clad layer is double that of the substrate. Wear test results reveal that the tribological performance of the WB-clad layer is superior to that of the Ti-6Al-4V substrate. This investigation also discusses the forming mechanism of the clad layer microstructure.
