Sažetak
The paper examined the wear of induction-hardened surfaces of stainless steels X20Cr13 and X17CrNi16-2, under combined wear conditions at a load of 100 to 300 N and a rotation speed of 382 to 754 min-1. The wear test was carried out on a tribometer with the use of an aggressive medium in the chamber according to the factorial experimental plan. After each wear cycle on the tribometer, the samples were exposed to corrosion action in corrosion test bath. Analysis of variance revealed a significant influence of rotation speed and load due to wear on the tribometer. Testing the difference in the mass loss values of the samples due to corrosion using the Mann–Whitney U test, did not show a significant effect of corrosion. Steel X20Cr13 showed greater resistance to combined wear, which had a 27% lower wear intensity compared to steel X17CrNi16-2. Its increased resistance can be attributed to the formation of a martensitic surface layer with dispersed carbides, which increases the resistance to abrasion, dynamic durability and fatigue of the surface of the protective layer.
