Preparation of Plating-Diffusion Composite Coating on Ti-Based Alloy

Abstract:

A composite coating was prepared on Ti-6Al-4V surface by the combination of nitriding, Mo-sputtering and sulfurizing treatments. The microstructure and phase constituent of the composite coating were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. Furthermore, the cross-sectional hardness gradient of the coating was determined. The results revealed that the composite coating consisted of Ti, Mo, MoS₂, TiN and transition layer and the grain size of the sulfides formed on the coating surface were different with treatment temperature. The examination of the cross-sectional hardness of the composite coating revealed that the coating was an ideal tribological surface.
