The effect of parameters burnishing rolling – pressuring process in aspect to technological quality surface layer of 316L stainless steel

In the manufacturing of machine elements was important to technological quality products. In surface engineering one of the economic and ecological treatments used for technological properties were burnishing rolling – pressuring process. This is a surface plastic forming a local plastic deformation based on the overall impression given by smooth and hard tool. In production, engineering cylindrical outer surfaces (e.g. plugs propulsion shaft centrifugal pumps seawater) were finishing. You can therefore propose burnishing in exchange for abrasive machining. The article presents the influence of parameters for burnishing rolling – pressuring process on the degree of relative strain hardening and surface roughness reduction ratio. Burnishing process carried out for 316L stainless steels. After the experimental study, it was determined that there was an increase in hardness and a decrease in roughness of the top outer cylindrical layer of stainless steel, which can be applied to the centrifugal pump shafts ship. Important question to determine in the article of the research was to receive appropriate technological quality. The burnishing due the technological and economic aspect in the production of machine parts in exchange for the abrasive processing can be used. After the experiments, it was found that the technical parameters are influenced by the hardness and the roughness of the outer cylindrical surfaces and the material ratio curve a convex shaped, which, taking into account the load capacity of the surface will be directly affected by its resistance to wear and corrosion of the surface layer.
