“…At a low sliding velocity (0.5 m s −1 ), the frictional heat produced between the pin and disc is lower when compared to 0.75 m s −1 & 1.0 m s −1 . Generally, the heat generation depends upon the sliding velocity, i.e., the increase in the sliding velocity could increase the frictional heat, and vice versa [29]. This frictional heat could play a vital role in the formation of the oxide layer.…”

The present research work demonstrates the effect of friction stir process (FSP) and its process parameters (rotation speed and travel speed) on the microstructure evaluation, microhardness and wear behaviour of FSPed AA6082. The microstructure characterization of the processed samples was examined using the Optical Microscope (OM). Dry sliding wear test was carried out by varying the sliding velocity (0.5, 0.75 and 1.0 m s−1) and applied load (5, 10 and 15N) using the pin on disc apparatus. Wear mechanisms experienced by the FSPed AA6082 were mapped, and the optimal FSP and wear parameters have been determined using Taguchi analysis. The results showed that there is a significant improvement in the microhardness (92 HV 0.3) and wear resistance for RS 1250 rpm & TS 40 mm min−1 due to the grain strengthening mechanism and microstructure modification. Formation of oxide layer played a crucial role on the wear resistance of the FSPed AA6082 and its significance has been discussed elaborately using the Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS).

“…In the case of Hardide CVD coatings the freshly polished material surface has high hardness which is in the range of 11 to 16 GPa. The oxide layer which is formed on tungsten in air (WO 3 ), has a reported hardness of between 4 and 7 GPa [30], which is significantly lower than the hardness of W/WC coating itself therefore preventing galling from happening [31]. The presence of such oxide is also noted to cause a reduction in friction as observed in CoF graphs where despite the presence of fine wear debris the friction is observed to reduce towards the end of the tests.…”

Nanostructured tungsten/tungsten carbide (W/WC) coatings produced by chemical vapour deposition are promising WC based coatings for applications where galling wear is prevalent due to the high hardness, toughness and stacking fault energy which the coatings possess despite low hardness to elastic modulus ratio (H/E). In this work the galling resistance of W/WC coatings has been studied through tibometer tests using sliding speeds of 0.014 m s −1 and contact pressures of up to 810 MPa. The study investigates the effects of surface finish and the use of similar and dissimilar material combinations on galling wear. Results show that self-mated stainless steel AISI 316 behave poorly under dry sliding wear conditions whilst uncoated stainless steel tested versus W/WC coating combinations are affected by galling due to material transfer forming a stainless steel on stainless steel tribosystem. The best performance was recorded for self-mated W/WC which did not develop any signs of galling even at the highest contact pressures (810 MPa) contradicting the common practice that the use of dissimilar materials can help prevent galling.
