OBRABOTKAMETALLOV Vol. 24 No. 1 2022 TECHNOLOGY Fig. 2. Three-dimensional profi lograms on a 0.9 × 1.2 mm area of the disk surface made of 03Cr16Ni15Mo3Ti1 steel, after fi nishing turning (a) and dry diamond burnishing with different forces Fb: 100 N (b), 150 N (c) and 200 N (d) a b c d a b Fig. 3. Dependence of the average values of the roughness parameter Ra (a) and the smoothing coeffi cient δRa (b) of the 03Cr16Ni15Mo3Ti1 steel surface on the burnishing force Fb depressions (indentation) during burnishing with increased loads may result from damage to the austenitic steel surface during its adhesive interaction with a diamond indenter without applying coolant lubricant. Microdurometry of the burnished surface, performed at loads of 0.49 N and 1.96 N with the Vickers indenter, showed a signifi cant effect of the smoothing force on the hardening of the surface layer
