Influence of oxidation of nitrocarburized steel upon the resistance to wear and corrosion

Results of investigation of influence of post-oxidation of nitrocarburised carbon steel of case hardening class upon the improvement of resistance to wear and corrosion have been reported in the contribution. Oxidation of test samples has been conducted in the oxidizing AB1 bath, subsequent to the nitrocarburising in the TENIFER salt bath. Test pieces have been subjected to corrosion and tribological investigation. Corrosion testing has been done applying electrochemical methods, while trobological testing included investigation of resistance to adhesion. The obtained results indicate favorable effects of post-oxidation of nitrocarburised layer upon both, resistance to adhesion wear and corrosion.
