The work aims to prepare NiCr-Cr3C2 coating with good tribological properties by electro-contact sintering on the basis of plasma spraying. The reinforced NiCr-Cr3C2 coating was deposited by electro-contact sintering after prefabricated on GH4169 alloy by plasma spraying. The phases, structure and interface of NiCr-Cr3C2 coating were analyzed by OM, SEM, XRD and EDS. Tribological properties of the coating were evaluated by ball-disk rotating friction and wear tester. The instantaneous heating of electro-contact sintering promoted the plastic deformation and heat diffusion of NiCr-Cr3C2 coating deposited and decreased the porosity from 5% to 2% and increased the adhesion strength from 46 MPa to 210 MPa. A complete friction layer was formed on the friction surface of coating at 400 ℃ and 600 ℃. The coefficient of friction decreased from 0.8 at 400 ℃ to 0.45 at 600 ℃ due to the components of eutectic fluoride. The coating appeared oxidative wear at 600 ℃. Electro-contact sintering can enhance the properties of NiCr-Cr3C2 coating such as higher bonding strength, lower porosity and friction coefficient. The coating exhibits better friction and wear behaviors at 600 ℃.
