In this study, Sn-0.7Cu solder alloy was reinforced with Al2O3 (50 nm) and ZrO2 (45 nm) nano particulates to form Sn-0.7Cu/Al2O3 and Sn-0.7Cu/ZrO2 composites. The volume percentge of the Al2O3 and ZrO2 nanoparticulate reinforcement was kept at 1.5%. The composites were synthesized using powder metallurgy technique assisted with microwave sintering and incorporating hot extrusion as secondary processing...
In the present work the concepts of the automated system of the technological support of a combined treatment based on the ion implantation, ion alloying, plasma-ion coating, and laser modification are shown. The influence of the technological parameters for all kind of the treatment, the physical and mechanical properties of the part material before the treatment, geometrical characteristics of the...
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,...
