Abstract
On test samples of stainless steels, there were conducted laboratory tests and also sample tests in real wear conditions. Electrochemical testings were made towards control of corrosion resistance of modifi ed steel surfaces. On test samples of stainless steels X20Cr13 i X17CrNi16-2, there were conducted metallographic analysis
and hardness testing. The possibility of applying modifi ed surfaces of selected steels was cntroled by sample testings in real wear conditions. Test bolts are welded with MMA procedure and it was used electrode Cr-Ni- Mn (18/8/6). Obtained results showed that induction hardened and post-nitrided martensitic stainless steels
achieveed for three orders of magnitude bigger wear resistance in relation to asreceived condition.
