Документ Experimental investigation of tribology-related surface topography parameters and hardness of 16MnCr5 case hardened steel(Національний технічний університет "Харківський політехнічний інститут", 2023) Nagy, NoraTribological properties are determinant in the functionality of contacting surfaces of machine elements. The wear resistance or load bearing capacity influence the lifetime of these parts. In this study tribology-related surface topography parameters (Ssk, Sbi) and the hardness of hard turned surfaces are analyzed after hardness and topography measurements. Correlation coefficients were calculated for their relationships. It was found that the cutting parameters affect the wear resistance and the hardness in the opposite direction.Документ Investigation of face milled surface topography on C45 workpiece assuming movement at 30° and 60° to feed direction(Національний технічний університет "Харківський політехнічний інститут", 2023) Nagy, Antal; Kundrak, JanosWhen surfaces with anisotropic texture are moved in different directions related to their assembled counterpart during operation, the friction conditions change, as they are determined by the lay of the topographies. In the article, contributing to the exploration of this characteristic, we analyze the inhomogeneity of the topography on a face milled plane surface with a symmetrical setting in sections at an angle of 30° or 60° to the feed direction. Roughness profiles are recorded at 13 pointslocated equidistantly from each other in each measurement plane, and the degree and distribution of the roughness deviations are determined on the surface.
