对比

A comparative study of porosity, oxide contents, bond strength and wear resistance of 3Cr13 stainless steel coatings deposited by high velocity and regular arc spray processes was carried out. An orthogonal and rotational regression experimental method and an ordinary single-factor experimental method were adopted to evaluate the coating hardness with respect to the effect of processing parameters. The quantitative formula of processing parameters with coating hardness was obtained by means of microcomputer.

摘 要：对比研究了3Cr13不锈钢高速电弧喷涂涂层和普通电弧喷涂涂层的孔隙率、氧化物含量、涂层结合强度和滑动磨损性能，并采用多因素正交旋转回归设计和单因素对比试验的方法研究了高速电弧喷涂工艺参数对3Cr13不锈钢涂层显微硬度的影响，用微机回归得到了喷涂工艺参数与涂层硬度之间的定量关系式。
