In the article were presented influence of technological parameters of burnishing process on the degree of hardness and reduction roughness. Burnishing process carried out for stainless steels X2CrNiMo17-12-2. The experimental research were obtained in the surface layer increase in hardness 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. The experimental research by application of the burnishing rolling – pressuring process (BRP) method were made in the Laboratory of Production Engineering at the Department of Marine Maintenance at the Faculty of Marine Engineering at the Gdynia Maritime University. After the studies it was found that the hardness of the surface layer and the roughness of the shaft necks an important influenced by technological parameters of processing (burnishing speed, feed and depth of burnishing). The objective of applying burnishing process may be, for example, the need to increase surface smoothness and dimensional accuracy of part. To achieve the objectives strengthen and smooth of burnishing stainless steel should be used the one pass burnisher roller and feed fn = 0.2 mm/rev and disk burnishing tool feed an = 1.0 mm and burnishing speed vn = 70 m/min.

The paper presents choice results of experimental testing of burnishing process by methods BRP – burnishing rolling – pressuring. The burnishing process is a technology of surface plastic forming of machine parts. The plastic deformations are called out by arrangement of strengths causing the superficial crossing the value of tension pressure of the materials. They set the on cold causing except moving the unevenness also the cold work in top layer of workpiece. Studies were conducted for burnishing process of the external cylindrical surfaces. Burnishing carried out for stainless steels. Burnishing technology was proposed using burnished roller (BR-01) in order to give adequate operational characteristics of the shafts neck centrifugal pumps. An important issue to resolve in the article of the research was to obtain appropriate technological quality, and because of the economic aspect of the production and regeneration of machine parts, burnishing applied in exchange for abrasive processing. In experimental studies were obtained in the surface layer increase in hardness and the Abbott-Firestone curve a convex shaped, which given load capacity of the surface will be directly affected by its resistance to wear and corrosion. The burnishing rolling – pressuring process (BRP) were decreased in surface roughness of the top outer cylindrical layer of stainless steel, which can be applied to the centrifugal pump shafts ship.
