The Study of Electrochemical Polishing HVOF Spraying Coating

Abstract:

Article Preview

HVOF WC-Co spraying coating can enhance greatly the anti-wear performance of workpiece, but it is just the high hardness of spraying coatings that makes the polishing of workpiece very difficult, the application of HVOF was limited. In this paper, we discuss the feasibility of apply ECP(electrochemical polishing) to spraying coatings, include the study of electrolyte, the optimization of machining parameters et al., the experiment results show that it is not only feasible that apply ECP to machining spraying coatings, but also high machining efficiency, high quality surface can be obtained. The surface roughness can be reduced from Ra=4.0μm to Ra=0.7μm with suitable machining parameters during a very short time.
