Abstract：The composite powder of Mo-(NiCr-Cr3C2) was mechanically blended and deposited using atmospheric plasma spraying. The mechanical property and tribological performance of the prepared coating were tested. The results show that the porosity and the microhardness of the composite coating are inversely proportional to the Mo content. The coating with the Mo addition of 20%(mass fraction) presents better performance in the frictional test. All the composite coatings mainly endures adhesive wear and abrasive wear. The coating containing large portion of NiCr-Cr3C2 is prone to flake during the wear. The wear resistance of the coating shows a good accordance with the index of H/E of the coating.
