Abstract

The features of materials alloying from gas and metallic plasma, as well as due to the mixing process in liquid phase are investigated in this study. Surface modification of Mo, W, Ni, TiAlN, FeB, Co-32Ni-21Cr-8Al-0.5Y, ZrO₂, Ti64, Hastelloy, WC-Co, and WC-Ni under pulsed plasma irradiation is analyzed. Results show that pulsed plasma treatment improves the physical (grain size, surface roughness, and porosity) and mechanical (hardness and wear resistance) properties of the exposed materials.
