A comparative study of porosity, oxide coontents, 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 patameters with coating hardness was obtained by means of microcomputer.The results show that, compared with the regular arc spray process, a dense?
