“…Moreover, at any given sliding distance, weight loss increases with applied load. Similar trend is also observed for other conditions, which is in agreement with other researchers [40][41][42][43][44][45][46][47][48][49][50][51][52]. The wear rate was calculated from the slope of the weight loss versus sliding distance.…”

Aluminum alloys are attractive for critical applications such as pistons, clutch housings and liners in automotive industry for their high strength to weight ratio, high corrosion resistance and good heat conductivity. These alloys can be fabricated using casting and powder metallurgy techniques in which porosity is a common feature. The presences of pores adversely affect the mechanical properties and wear resistance of these components. Not only the total area percentage of porosity influences the degradation in properties but also size, shape and interconnectivity of pores play an important role. In this study, aluminum alloys were produced using powder metallurgy technique. The amount of porosity was varied by varying compaction pressure and amount of wax added before compaction. Reciprocating wear tests (ball-on-flat configuration) were performed against AISI 52100 bearing steel ball under both low (1.5-5N) and high (6-20N) loads. Scanning electron microscopy was employed in order to identify possible wear mechanisms. Both detrimental and beneficial effects of porosity under different loading conditions were observed. An attempt has been made to develop a relationship between pore size and distribution and wear behavior of aluminum alloys.

“…Dry sliding wear tests have been carried out using pin-on-disc wear test rate normal loads of 5, 7, 9 and 11 Kgf and at constant sliding velocity of 1.0 m/s. The best results have been obtained at 20% weight fraction of 320 grit size SiC particles for minimum wear [18].…”

“…Friction and wear characteristics of Al-SiC composites have been investigated under dry sliding conditions and compared with those observed in pure aluminium. The best results have been obtained at 20% weight fraction of 320 grit size SiC particles for minimum wear [18]. Glow discharge (GD) nitro carburizing, at low carbon content and different working temperatures, was performed on AISI 316L and AISI 304 stainless steels.…”

Recent thermal spray processes such as plasma spraying are usually employed to deposit NickelChromium coatings onto the AISI 316 steel substrates to improve the wear resistance. Ni-base alloys, which are widely used to obtain wear resistant coatings, are usually heat treated after thermal spraying to improve their tribological properties. The dry sling wear experiments were carried out in pin on disc tribometer at room temperature 35 °C (308 K), 150 °C (423 K), 250 °C (523 K) and 350 °C (623 K) against medium carbon steel (EN8). The worn surfaces were examined by X-ray diffraction and SEM (Scanning Electron Microscopy) with EDS (Energy dispersive spectroscopy). The applied load was 40 N and sliding speed was 2 m/s. In 350 °C, the wear rate was marginally lesser than the rest of the temperatures due to the initiation of oxide layer formation, which was also substantiated by SEM and EDS. Fe peaks and O peaks were found scarcely. Few Fe peaks were also predominantly noticed by EDS analysis. The presence of Fe 3 O 4 in the tribolayers formed during sliding wear acted as a protective film to retard the wear rate in terms of mass loss.
