Abstract:

This paper deals mainly with the formulation, processes and microstructure of the diffusion Vanadium-coating with powder on the journal bearing steel of cone bits. The diffusion Vanadium-coating has been observed and analyzed with the scanning electron microscope, the microstructure of the diffusion coating has been identified by X-ray diffractometer, and the mechanism of the formed coating has preliminarily been studied in this paper.

Key words: Cone bit, Bit bearing, Powder, Vanadium-coating
