Notes:
Cr3C2-NiCr compound coating was acquired on 20 steel substrate by plasma sprayingprocess. The microstructure of the coating is dense with low porosity. Carbide lamellartiy inlaysinto the nickel-base solid solution in the coating. Main phases of the coating are Cr3C2, Cr23C6,Cr7C3 and nickel-base solid solution, etc. Average microhardness of the coating is aboutHV0.1756.9. Microhardness of some ceramic phases in the coating is as high as HV0.11113, whichhelps to the improving of wear resistance of the coating. The wear-resisting property of the coatingis good under grain-abrasion condition and excellent under lubricated wear condition
