抄録
A composite coating containing WC/12Co cermet and Fe₄₃Cr₁₆Mo₁₆C₁₅B₁₀ metallic glass was successfully deposited onto type 304 stainless steel by high-velocity oxygen fuel (HVOF) spraying, and the microstructure and tribological properties were investigated. The microstructure of the coating was characterized by scanning electron microscopy/electron probe micro-analysis (SEM/EPMA) and X-ray diffractometry (XRD). The hardness and tribological properties of the coating were tested with a Vickers hardness tester and reciprocating wear tester, respectively. The composite coating, in which flattened WC/12Co was embedded in amorphous Fe₄₃Cr₁₆Mo₁₆C₁₅B₂₀ layers, exhibited high hardness, good wear resistance and a low friction coefficient compared to the monolithic coating. The addition of 8% WC/12Co to the Fe₄₃Cr₁₆Mo₁₆C₁₅B₂₀ matrix increased the cross-sectional hardness from 660 to 870 HV and reduced the friction coefficient from 0.65 to 0.5. WC/12Co reinforcement plays an important role in improving the tribological properties of the Fe₄₃Cr₁₆Mo₁₆C₁₅B₂₀ coating.

A composite coating containing WC/12Co cermet and Fe₄₃Cr₁₆Mo₁₆C₁₅B₁₀ metallic glass was successfully deposited onto type 304 stainless steel by high-velocity oxygen fuel (HVOF) spraying, and the microstructure and tribological properties were investigated. The microstructure of the coating was characterized by scanning electron microscopy/electron probe micro-analysis (SEM/EPMA) and X-ray diffractometry (XRD). The hardness and tribological properties of the coating were tested with a Vickers hardness tester and reciprocating wear tester, respectively. The composite coating, in which flattened WC/12Co was embedded in amorphous Fe₄₃Cr₁₆Mo₁₆C₁₅B₂₀ layers, exhibited high hardness, good wear resistance and a low friction coefficient compared to the monolithic coating. The addition of 8% WC/12Co to the Fe₄₃Cr₁₆Mo₁₆C₁₅B₂₀ matrix increased the cross-sectional hardness from 660 to 870 HV and reduced the friction coefficient from 0.65 to 0.5. WC/12Co reinforcement plays an important role in improving the tribological properties of the Fe₄₃Cr₁₆Mo₁₆C₁₅B₂₀ coating.
