Microstructure and Cavitation Erosion Behavior of Carbide-Based Coating Deposited by Electrical Arc Spraying

Abstract:

Two different martensite stainless steel 1Cr17/Carbide-based coatings (C-1 and C-2) were prepared by electrical arc spraying technique. Microstructures of the coatings were investigated by optical microscopy (OM), X-ray diffraction (XRD), scanning election microscopy (SEM). The results show that the C-2 coating has higher hardness and finer structure than the C-1 coating. The cavitation erosion resistance was tested using a China GB6383-86 standard method in fresh water. The cavitation erosion mass loss of the C-2 coating was only 55 percent that of the C-1 coating eroded 15h, the C-2 coating has better cavitation erosion resistance.
