Plasma Surface Alloying

The Ni modified layer was prepared on surface of the Ti6Al4V substrate by plasma surface alloying technique (PSAT). The cross-section micro structure, phase structure and microhardness of Ni modified layer were studied. The friction and wear behavior of the Ni modified layer and the Ti6Al4V substrate were analysed. The effects of displacement amplitude, frequency and fretting time on friction coefficient of the Ni modified layer were investigated. The results indicated that the wear rate was lower compared with that of the Ti6Al4V substrate. Friction coefficient of the Ni modified layer increased with the increase of frequency. But it was insensitive to the change of wear time and the displacement amplitude. The wear mechanism of the Ti6Al4V was adhesion and abrasion wear mechanism while the Ni modified layer showed slightly abrasion wear.

Carbon Fillers

In this study, the influence of different carbon fillers on the tribological and manufacturing properties of the thermoplastic polyamide PA6 is presented. The following materials were used as carbon additives: glassy carbon (GC), carbon obtained from the pyrolysis of polymer wastes (BC), and graphene oxide (GO). Fillers were introduced into the PA6 matrix by mechanical stirring in alcohol to settle carbon particles onto the granule surface. Samples were made by injection molding from the produced granules. The microstructure, hardness, and melt flow index (MFI) of the prepared materials were determined. Also, the degree of crystallinity of the samples was examined by Differential Scanning Calorimetry (DSC) and X-ray Diffraction (XRD). The melting point (Tm) was examined using DSC, the results from which allowed the correct heat treatment of PA6 to increase the crystallinity of the obtained material to be selected. The dry sliding tribological behavior of the composites was evaluated via pin-on-block tests against cast iron counterparts. The tests were performed at room temperature, with a sliding speed 0.1 m/s, a sliding distance of 250 m, and a normal force of 40 N. The obtained results revealed that the introduction of GO into the PA6 matrix provides favorable wear behavior, such as the formation of debris that acts as rollers that give a decrease in wear and a lower coefficient of friction. The coefficient of friction in samples with graphene oxide was nearly two times lower than with other samples. However, the ease of manufacture of this material was drastically reduced compared to GC or BC fillers. Microstructural investigations of wear tracks revealed poor adhesion between the polymer matrix and micrograins of carbon fillers (GC and BC), and therefore their influence on tribological properties was less compared to graphene oxide.
