THE EFFECT OF POISED MAGNETIC TREATMENT OF NITRIDED STEELS FOR WEAR-RESISTANCE

Surface engineering approach to increase surface properties such as wear resistance performed by pulsed magnetic treatment of nitrided steels was studied. Selected steel surfaces were treated by pulsed magnetic treatment and plasma ion nitriding with different optimized process parameters. The obtained microstructures were examined to study the influence of magnetic treatment on ion nitriding. SEM, AES, microhardness measurements, and image analyser were used to characterize the surface and interface. The results of this study show that pulsed magnetic treatment reduces residual stresses on the surface, improves the bonding of deposited nitride layers to substrate, influences the nitride layers, case depth, and surface hardness formation and increases the wear resistance.
