“…In the equations, an increase in wear rate is denoted by a positive sign, whilst a decrease in wear rate is denoted by a negative sign. The R 2 values of 98.05 and 97.57 respectively show that only 5% of the data deviated and the developed model can envisage the rate of wear with a high level of accuracy, specifically a 95% degree of accuracy [57].…”

This study aimed to investigate the tribological and microstructural characteristics of LM26 composites reinforced with silicon carbide to evaluate their suitability for high-temperature applications. For the sample fabrication, the modified stir-casting method was optimized using a Taguchi L16 orthogonal array. The wear rate and friction behavior were evaluated using the Taguchi's S/N ratio analysis. When SiC was incorporated into the composite, the wear resistance increased by up to 15 wt. %. The wear resistance of the LM26/SiC composite was improved compared to that of the pure LM26 aluminum alloy. The results of this study provide useful information to improve the wettability of metal matrix composites made from commercial-grade LM26 aluminum alloy by adjusting the SiC weight percentage. This type of composite has the potential as a replacement material for traditional applications such as heat sinks, heat exchanger fins, and electronic packaging.

“…Comparing the FEM results to well-known experimental findings is the most convincing method of verifying the results. The simulated result in this research is compared with Kumar and Kumar [28]. The wear simulation is run by considering the models proposed by Archard that accept the linear wear law shown in equation (3).…”

“…Many literatures enlightened that in the Archard wear model, the wear rate of the material in inversely proportion to the hardness of the material [15,31,32]. In recent research, Kumar and Kumar [28] explained that the mechanical properties, such as tensile strength and hardness of the composite material increased by 23% and 53.33%, respectively, for 5% of ZrB 2 and 2% of fly ash for AA7075 HAMMCs. The simulated results show that the material's wear rate decreases after increasing the wt.% of the ZrB 2 .…”

This work aims to analyze the wear properties of the hybrid aluminum metal matrix composites (HAMMCs) using finite element analysis (FEA). A dry sliding linear reciprocating wear model is analyzed using ANSYS 19.1. Aluminum 7075 alloy and Hybrid aluminum metal matrix composite reinforced with ZrB2 (1, 3, and 5wt.%) and fly ash (2wt.%) is taken as sample material. A steel ball (EN 52100) is utilized as counterpart in the study of dry sliding wear properties. The deformation of the steel ball during the wear process is assumed as negligible. Under various circumstances, a 3D point-to-surface connection is built to analyze the dry sliding wear process. The wear depth, contact pressure and wear volume are analyzed using finite element analysis. The analytical results are compared with the experimental results with the help of ANSYS to analyze the process parameters. The ANOVA analysis is employed for optimization, which exhibits that the load had the greatest impact on the material's wear rate, followed by the material's composition and temperature. The wear depth, wear rate and contact pressure at optimum input parameters for the HAMMCs are 0.47µm, 11.31×10-6 mm3/Nm and 0.33MPa respectively. The Simulated results support the experimental results, and the average error is 9.82%.
