【Abstract】 In order to determine the spraying process parameters of 3Cr13 for rapid tooling making, an orthogonal experiment was used to study the effects of spraying process parameters on coating thickness, coating hardness and porosity. The microstructure of spraying coating was observed and analyzed by optical microscope and electron microscope. The results show that: the spraying rapid tooling was manufactured successfully by the obtained spraying process parameters, and can be used in the manufacturing of cover panel.更多还原
