“…As shown in Fig. 5, the WSD increased with the increasing load, which may have resulted from the destructive probability of asperities of the rubbing surfaces under higher pressure [24]. Compared with the pure PAO6, the PAO6 with nanocomposites had a smaller WSD under a moderate load of 20 N, especially at the mass concentration of 0.01%.…”

In the present work, two types of novel nano additives, titanium sulfonate ligand/black phosphorus (TiL 4 /BP) and titanium dioxide/black phosphorus (TiO 2 /BP) nanocomposites, were prepared. The tribological behavior of the steel/steel friction pairs lubricated by polyalphaolefins type 6 (PAO6) containing the nanocomposites under boundary lubrication was studied. The worn surfaces were analyzed using modern surface techniques. The experimental results show that the rubbed surfaces became smooth and showed little wear with the addition of the nanocomposites. TiO 2 /BP nanocomposites can significantly improve the lubricity of BP nanosheets under high contact stress. The synergistic roles of the load-bearing abilities and rolling effect of TiO 2 nanoparticles, the slip induced by the BP with its layered structure, and the establishment of a tribofilm on the sliding interface are the basis of the tribological mechanisms.

The aim of the present work is to investigate vickers hardness, wear behavior as well as to perform optimization of wear data for pure Al and Al-Al2O3-TiO2 hybrid metal matrix composites. The hybrid composite (Al-Al2O3-TiO2) was prepared by mechanical stir casting with equal proportion of reinforcement (2.5, 5.0, 7.5 and 10 wt.%). Vickers hardness, wear behavior and its optimization using ANOVA as well as TOPSIS along with the microstructure of the worn surface of prepared sample has been investigated. Vickers hardness increases with an increase in weight percentage of reinforcements. Wear test was carried out under dry sliding condition by pin-on-disc wear machine according to the ASTM G99-95a standard. Wear properties of the sample have been obtained at different percentages of reinforcement. Wear resistance of the hybrid composite increases with the variation of percentage of titanium oxide particles due to its lubricating properties. ANOVA shows that the reinforcements and load have different effect on samples wear rate. TOPSIS analysis shows rank of the sample according to its wear rate. Worn surface morphology was investigated and it showed deep grooves, more debris, delamination and rough surface in pure Al sample as compared to the high percentage of reinforced hybrid metal matrix composites.

“…The wear of cooperating elements with each other has being a focal point of interest for a long time [1][2][3]. The following articles show the various approaches to engineering solutions for improvement of wear elements [4][5][6][7][8][9][10]. Machinery for using machinery components is the inseparable effect of the device.…”

The friction process in the tribography systems causes both energy losses and consumption process losses. The layer of the surface of a solid body differing from the material to the entire volume of the solid is a close participant in the tribological process. The effects of external influences during treatment of the material and in friction processes were established and modified. The well-shaped layer of the surface provided optimum tribological properties during operation. This work provides an analysis of the use of a tribological pair working in a rotational movement, in different operating conditions. The tests carried out showed the impact of the selected exploitation factors, that is, the speed and load, the consumption and the friction coefficient of the saliva and the graphical interpretation of results from the results obtained from experimental and metallographical studies. The tests carried out in the block-on ring position of the T-05 tribology was the nature of preliminary tests. Preliminary tests enabled
