| Abstract |
Cr3C2-NiCr compound coating was acquired on 20 steel substrate by plasma spraying
process. The microstructure of the coating is dense with low porosity. Carbide lamellartiy inlays
into 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 about
HV0.1756.9. Microhardness of some ceramic phases in the coating is as high as HV0.11113, which
helps to the improving of wear resistance of the coating. The wear-resisting property of the coating
is good under grain-abrasion condition and excellent under lubricated wear condition. |
