Abstract

It can be found that improving the wear and corrosion resistance properties of workpiece is one of the most important methods to enhance its life in terms of the damages of mechanical equipment in die industry and metallurgy. The PTAW deposited resistance overlays is the key direction at present. In present paper, the Co-based self-fluxed high-temperature alloy coatings were fabricated with the method of orthogonal experiment by using PTAW process, the relationship between the mass energy and the dilution rate is discussed. The influence of process parameters on deposited overlays. The influence of three parameters welding current, welding speed and feeding rate on hardness, wear resistance and dilution rate of the coatings was explored in detail. Optimal parameters for wear resistance coating is given as below: spray current is 60 A, powder flow is 23.5 g/min and welding speed is 80 mm/min.
