The results of studies of changes in the fine structure of the surface layer and tribological properties of parts made of the QT steel 41Cr4 after finish-turning operation depending on composition and thickness of the PVD coating on changeable carbide blades are described. Correlations between the parameters of fine structure, the residual stresses of a surface layer, the coefficients of friction, and the wear rate of the machined surface are determined.

Key words: fine structure, QT 41Cr4 steel, finish turning, PVD coatings.
