To improve the capability of abrasion-resistance of the grinding roller, the NiCr-Cr3C2-Ti-C compound welding surface is prepared and taken NiCr foil, Cr3C2 powder Ti powder and C powder as raw materials based on TIG method. The phase structure, microscopic organization, component distribution and the hardness are studied by SEM, EDS and XRD. It is shown that the welding tissue is composed by Ni-based sosolid, TiC and Cr23C6 etc, and its highest hardness is between 1800 and 2000 HV. By wearing test, the abrasion of NiCr-Cr3C2-Ti-C compound welding surface and the other materials are compared. It is shown that the NiCr-Cr3C2-Ti-C compound welding surface has better abrasion-resistance than the other materials, and can be used to improve the capability of abrasion-resistance of the grinding roller.
