“…The results indicate that the phase composition of the composite surface is complex. As shown in Figure 4, the strong diffraction peaks of Cu and Sn and the weak diffraction peak of Ni are detected, while the weak peaks of Cu x Sn y are appeared, which is similar to the research results in literature (Radhika et al , 2018). In M9, the weak diffraction peaks of MoS 2 is detected and the peaks of Cu x S y (the main components are Cu 2 S, Cu 7 S 4 , etc.)…”

“…The direct addition of MoS 2 claims to have specific functions or supplement to keep physical association on the bonding interfaces between the matrix and MoS 2 , and the MoS 2 on the interface is easy to peel off under high temperature and heavy load, which can weaken the performance of copper matrix composites (Xiao et al , 2017; An et al , 2016; Moazami-Goudarzi and Nemati, 2018). Above all, the solid solution strengthening matrix materials can be formed through adding alloying elements such as Zn Ni, Sn and Fe; meanwhile, the mechanical properties of matrix materials can be improved by surface plating (Varol and Canakci, 2015; Senthil Kumar et al , 2013; Zou et al , 2018; Radhika et al , 2018; Zhang et al , 2016). It is effective to improve the interface adhesion, mechanical properties and tribological properties by adding MoS 2 into Cu-Fe, Cu-Sn alloy or copper-plated alloy (Varol and Canakci, 2015; Peng et al , 2017; Fu and Wang, 2010).…”

Purpose The purpose of this paper is to investigate the friction and wear mechanisms in copper-based self-lubricating composites with MoS2 as the lubricating phase, which provides a theoretical basis for subsequent research on high-performance copper-based self-lubricating materials. Design/methodology/approach Friction tests were performed at a speed of 100 r/min, a load of 10 N, a friction radius of 5 mm and a sliding speed of 30 min. Friction experiments were carried out at RT-500°C. The phase composition of the samples was characterized by X-ray diffraction of Cu Ka radiation, and the microstructure, morphology and elemental distribution were characterized by scanning electron microscopy and energy dispersive spectroscopy. Reactants and valences formed during the wear process were analyzed by X-ray photoelectron spectroscopy. Findings The addition of MoS2 can effectively improve friction-reducing and anti-wear action of the matrix, which is beneficial to form a lubricating film on the sliding track. After analyzing different changing mechanism of the sliding tracks, the oxides and sulfides of MoS2, MoO2, Cu2O, CuO and Ni(OH)2 were detected to form a synergetic lubricating film on the sliding track, which is responsible for the excellent tribological properties from room to elevated temperature. Research limitations/implications For self-lubrication Cu–Sn–Ni–MoS2 material in engineering field, there are still few available references on high-temperature application. Practical implications This paper provides a theoretical basis for the following research on copper-based self-lubricating materials with high performance.

“…The test specimen surface becomes work-hardened when the load is increased to 15 N, and the hardened asperities function as an abrasive coating between the counter disc and specimen interface, causing the attrition rate to increase. 54,55 When comparing the wear rates of LM25 and hybrid MMC aged at 155°C, hybrid MMC has a lower wear rate. This can be explained by the fact that the hybrid MMC has a greater resistance to wear, which can be attributed to the presence of reinforcing particles, such as SiC and Al 2 O 3 , in the matrix.…”

The demand for hybrid composites has lately increased due to their extraordinary qualities, which include unique mechanical, tribological, and physical capabilities not found in other materials. These composites improve performance and utility by mixing different reinforcing components, making them highly sought after. However, there is a study gap on the effects of long-term ageing on the tribological characteristics of LM25 (Al–6.6Si–0.2Mg)/Al2O3/SiC metal matrix composites (MMCs). As a result, extensive studies on the influence of ageing temperature on the tribological properties of LM25/Al2O3/SiC MMCs via long-term ageing effects still need to be included. Therefore, this study investigated the metallurgical and hardness properties of stir-cast LM25 alloy reinforced with Al2O3 and SiC particulates with varying ageing temperatures. Furthermore, dry sliding wear behaviour is also examined. The investigation concluded that adding micron-sized Al2O3 and SiC particles to LM25 improves hardness and tribological properties. As the ageing temperature increased, the eutectic particles became coarser. Furthermore, the result illustrates that the coefficient of friction (COF) values also enhanced with wear rates. Higher loads increased the wear rate and COF, whereas higher sliding speeds decreased the COF and wear rate.

“…The melting of the alloy was conducted using an electrical arc furnace in a clay graphite crucible. Varying wt.% of Co was introduced into A356 alloy by adding the corresponding mass of pure Co into the crucible with Al ingot and was melted at a temperature of 754 0 C. The melt was stirred using a stirrer at 150rpm for 8 minutes [24] in order to obtain homogenous mixing of the alloying element in to the LM 25 ingot. Subsequently, the melt was poured into a permanent mold die made of oil-hardened non shrinkage steel at a temperature of 675 0 C and holding time was 30 seconds to obtain cylindrically shaped specimens with length 150 mm and diameter of 16 mm.…”

Aluminium alloys have found application in many areas like aerospace industries and automobiles specifically in Machine tool parts, aircraft wheels, pump parts, marine hardware, valve bodies and automotive pistons, owed to their strength to low weight ratio. The present study deals with the growing demand for more durable aluminum alloys for the engine components with improved mechanical property/ tribological properties majorly focusing on the area of wear and tear in engine piston systems. In the present research, the simultaneous effect of cobalt (Co) addition and wear testing factors on the wear resistance of Al-6.6Si-0.4Mg hypoeutectic alloy is investigated through response surface methodology (RSM), a system employed in the design of experiments. Using Minitab software, the regression analysis was done and an equation was formulated to forecast the wear rate and also to investigate the significance of each experimental parameter on the subsequent wear rate. It was found from the current research that, with a surge in the cobalt content, the wear resistance of the alloy increased. It was also noted that, the wear rate was found to increase with an increase in the sliding velocity and load. Whereas, wear rate decreases with an increase in the sliding distance. In order to obtain the minimal wear rate, optimal values for each parameter were found out. FESEM investigation was conducted on the worn-out specimen to evaluate the worn-out surface of the regular and modified alloy for different wear testing conditions.
