Processes of the burnishing can be used to production and regeneration of many elements of par t of shipping machines. The cylindrical external surfaces be regenerated often (the Journal of drive shaft and crankshaft). The burnishing is the cold plastic working; it marks with cleanness and the speed of process as well as the possibility of easy applying in practice. Across she pressing it can be applied to processing of cylindrical external surfaces processing and internal, flat and about different shapes. Examinations have been carried out for C45 steel with the use of fixed load furnisher NK-01 constructed in Department of Marine Materials and Technology. The research results have been presented in the paper and served as a basis for defining which parameters and values have greatest influence on the obtained hardness of the burnished surface. Finally conclusions related to the influence of burnishing on surface layer strengthening of a treated material have been drawn taking into account the results obtained in the research. The influence of effective strain on stereometrical properties and strain hardening at the surface layer of steel C45 after surface plastic working (burnishing) is presented. Characteristic features ofburnishing technology are a lack of thermal phenomena, simplicity of use and low-cost application. Burnishing is a technology used for the production and regeneration of parts of marine machinery, for example, can be used in the manufacture or repair of shafts and crankshafts as finishing. These papers present the influence of technological parameters of burnishing on strain hardening and surface roughness reduction ratio of ship machine elements surface layer.
