Problems of surface quality of ground hardened steels during dynamic load
This article deals with problems of changes of surface integrity components of ground hardened steels. Experiment fundamentals is samples preparation from hardened steel material by grinding at different cutting conditions, evaluation of origin values of surface integrity components and subsequently dynamic load in different surrounding. Changes of surface integrity components are monitoring in depending on dynamic load cycles count and kind of surrounding, in which to the load happened. Quality of surface and surface layer is dependence on cutting conditions a subsequently on surrounding in which will the components work. Evaluation of quality surface and product manufacture qualities are determinants factors for objective and correctly appreciation proprieties of components. From this experiment deduce conclusion, that aggressive surrounding isn’t always unprofitable for material. This experiment showed, that in evaluation of quality surface and surface layer due to roughness, roundness and residual stress achieving same values while using oil supply in corrosion surrounding as while dynamic load in normal surrounding.
