“…The 20CrMiTi pin against nonchroming T10 disc would be more softened and worn than the pin against the chroming friction pair [24]. Hence, the microstructures ( Figure 5) also confirmed the opinion stated above that only two layers existed in 20CrMnTi pin against the nonchroming T10 disc, compared with the three layers in the 20CrMnTi pin against the chroming T10 disc.…”

The microstructures of subsurface layers of 20CrMnTi steel pins against chroming and nonchroming T10 under dry sliding tests were studied by means of OM (optical microscopy), XRD (X-ray diffraction), and SEM (scanning electron microscopy). Results showed that the chroming coating strengthened the disc surface and significantly affected microstructural evolution. Three layers-the matrix, deformation layer (DL), and surface layer (SL)-formed in 20CrMnTi for the chroming T10. The matrix and deformation layer (DL) formed in 20CrMnTi for the nonchroming T10. The formation of the microstructure was considered as a result of the shear deformation.

“…Straffelini et al [11] studied the influence of load and temperature on the dry sliding wear behavior of Al-SiC p composites against frictional materials. They found that at higher temperatures, the frictional materials softened and formed a layer on the Al-based MMC disc, which increased the wear resistance of the MMC disc.…”

In this article, the effect of temperature and load on the dry sliding wear behavior of an Al-7Si alloy reinforced with in-situ TiB 2 particles is reported. The coefficient of friction and wear rate of Al-7Si alloy and in-situ composites were measured using a high-temperature pin-on-disc apparatus. The wear tests were performed in the temperature range of 100°C to 300°C, at an applied load of 40 to 120 N. With increasing temperature, the wear rate of Al-7Si alloy increased drastically and it decreased with the increase in weight percent of TiB 2 particles. The transition from mild to severe wear for Al-7Si alloy was observed at 80, 60, and 40 N at temperatures of 100°C, 150°C, and 200°C, respectively. The alloy reinforced with 5 wt pct of TiB 2 showed the transition at 120 N and 200°C, and the transition load further decreased to 80 N at 300°C. However, within the present experimental range of load, the addition of 10 wt pct of TiB 2 showed the transition only at 100 N and 300°C. The addition of TiB 2 particles increases the wear resistance properties of Al-7Si alloy even at high temperature.

“…With increase in sliding speed, friction coefficient increased [24,27] whereas Onat [28] reported that friction coefficient of Al-SiC decreased with increase in sliding speed. Thus, for variation of load, friction coefficient value increased [16,18,19,24,25,27] in some studies and decreased [1,11,17,28] in other cases. This indicates that the relation between applied load and coefficient of friction is not monotonic.…”

“…The effect of applied load was studied using applied load range of 10-110 N [14][15][16][17][18][19][20][21][22][23][24][25]. Some of the researchers used high load range to study the wear behaviour.…”

Tribological behaviour of Al-SiC metal matrix composites prepared using two different fabrication techniques, viz. sand cast and squeeze cast techniques are studied in a multi-tribotester (TR-25, DUCOM, India) under dry sliding conditions and ambient atmosphere for varying volume fraction of reinforcement, applied load and sliding speed. Friction increases with increase in applied load and sliding speed and volume fraction of reinforcement. Wear test results show increased wear rates at higher load and speed, while increase in SiC volume fraction yields decrease in wear rate. Corrosion study conducted in 3.5 % NaCl solution shows that squeeze cast composites have better corrosion resistance than sand cast composites.Vickers's microhardness test shows improved hardness properties for squeeze cast composites compared to sand cast ones. The microstructure study of wear tracks reveals domination of abrasive wear with minor traces of adhesive wear.
