摘要：

A wear resistant Cr13Ni5Si2-based metal silicide coating was fabricated on a substrate of titanium alloy BT20 by laser cladding process of Cr-Ni-Si alloy powders. Wear resistance of the coating was evaluated under block-on-wheel dry sliding wear test conditions at room-temperature. Microstructure of the coating is consisted of Cr13Ni5Si2 primary dendrites and small amount of Cr13Ni5Si2/Cr3Ni5Si2 eutectics. The laser-clad Cr13Ni5Si2-based coating exhibited an excellent wear resistance under dry sliding wear test conditions.
