Plasma nitriding is an effective surface treatment to improve unsatisfactory wear properties of machine elements. Such machine elements may also subject to magnetic fields in many industrial applications. Therefore, AISI 4140 ferromagnetic steel samples were plasma nitrided. Then, the samples were quenched in water and then post-aged at a temperature of 400°C for 30 and 120min in plasma environment...
Numerous machine components are constantly subject to different magnetic fields mainly due to the environments they are in, and they show some wear process throughout their life time. To understand this wear process better, the effect of magnetic field on the tribological properties of AISI 4140 steel has been investigated by applying different magnetic field intensities. One of the important factors...
Different kinds of diffusion processes, plasma nitriding, oxidizing and oxynitriding as of a combination of other two, have been applied to Ti6Al4V alloy to evaluate the effect of treatment times (1 and 4h) and temperatures (650 and 750°C) on wear properties of the alloy. It was observed that a hard modified layer was produced on the surface of the alloy after each diffusion process. While TiN and...
MoS 2 Ti composite films were deposited on silicon wafers and AISI 440C steel substrates with different target currents and working pressures by closed field unbalanced magnetron sputtering (CFUBMS). The composition of MoS 2 Ti films was determined by EDS. Crystallographic properties of MoS 2 Ti composite films produced were investigated by XRD and the friction and wear properties...
