Abstract
As a result of experimental and statistical modeling, dependencies were obtained that establish the effect of polishing modes (the number of passes of the polishing wheel, the value of the wheel tightness) on the roughness and thickness of the chrome coating obtained by the method of deformation cladding with a flexible tool. It was found that within the selected intervals of variation of the factors, an increase in the tightness of the polishing wheel and the number of passes of the wheel leads to a decrease in both the parameter of the roughness Ra and the thickness of the coating, however, with different degrees of intensity. The number of passes of the polishing wheel has a decisive effect on the value of the surface roughness of the clad layer after polishing. The effect of polishing modes on the thickness of the cladded coating is more complex, since it is demonstrated both in the individual comparable influence of both factors and in their interaction. The optimal modes of polishing of hydraulic cylinder rods subjected to chromium plating by the method of deformation cladding with a flexible tool have been determined. After the experimental check in the conditions of JSC “Minsk Automated Lines Plant named after P.M. Masherov” (Republic of Belarus), the established technological modes of polishing were added to the technological process of chromium plating of rods. It confirms the effectiveness of using the calculated dependencies.
