“…When a greater load is imposed, the contact pressure along the interface of the sliding components is elevated, resulting in an increase in adhesion across the pin and disc. The occurrence of cracks is facilitated by the heightened adhesive force in the direction of sliding 48 – 50 . Increased friction at the contact during extreme conditions leads to the displacement of particles, resulting in the formation of cavities, as illustrated in Fig.…”

The present investigation focuses on the fabrication of Copper-High Entropy Alloy (HEA) surface Metal Matrix Composite (MMC) using the solid-state Friction Stir Process (FSP) and the characterization of wear characteristics. Higher hardness values at the level of 770HV were the cornerstone in its selection, in addition to identifying several appropriate considerations for combining the AlCoCrCuFe HEA in Cu-HEA surface MMCs. Because of the combination of FSP and HEA, the produced composite had a fine microstructure and increased hardness. The wear test is carried out using pin-on-disc equipment for all conceivable parameter combinations to thoroughly analyze wear qualities, with velocity, load, as well as sliding distance chosen as input parameters. The wear rate decreases dramatically with HEA additions and rises with sliding velocity, load, and sliding distance. The impact of HEA addition on the Coefficient of Friction (CoF) during a dry sliding wear test is opposed to its influence on wear rate. The wear parameters such as load, sliding speed, and sliding distance possess a positive correlation with the wear rate and a negative correlation with a coefficient of friction. The applied load has a severe effect on wear rate and CoF when compared to other wear parameters considered. Scanning Electron Microscope (SEM) micrographs of the worn surface were utilized to analyze the wear process, which clearly showed that the copper’s wear resistance improved with the addition of HEA.

<div class="section abstract"><div class="htmlview paragraph">Lightweight materials are in great demand in the automotive sector to enhance system performance. The automotive sector uses composite materials to strengthen the physical and mechanical qualities of light weight materials and to improve their functionality. Automotive elements such as the body shell, braking system, steering, engine, battery, seat, dashboard, bumper, wheel, door panelling, and gearbox are made of lightweight materials. Lightweight automotive metals are gradually replacing low-carbon steel and cast iron in automobile manufacture. Aluminium alloys, Magnesium alloys, Titanium alloys, advanced high-strength steel, Ultra-high strength steel, carbon fiber-reinforced polymers, and polymer composites are examples of materials used for light weighing or automobile decreased weight. The ever-present demand for fuel-efficient and ecologically friendly transport vehicles has heightened awareness of lowering weight and performance development. Titanium alloys properties are increasing in the variety of applications in automotive parts such as fuel tanks, exhaust pipes, engine parts such as connecting rods, engine valves, reinforcing and stiffening parts, sub frames, body panels, fuel cell components, and electrification components. Motorcycles and automobiles that demand high dynamic performance, such as racing cars and bikes, commercial vehicles, and cargo trucks, must increase time on the circuit and have a good reaction. As a result, titanium alloys are frequently used to significantly reduce weight while increasing the performance output of automotive systems. The innovative investigation of titanium metal matrix (Ti-6Al-4V) composite with added multi reinforcement of tungsten carbide particles (WCp) and graphite particles (Grp) were examined on its tribological behavior. The Ti-6Al-4V built-in different composites Ti-6Al-4V/4%WCp/4%Gr and Ti-6Al- 4V/8%WCp/8%Gr with a size of WCp and Gr was 44μm and 15μm invented through stir casting. The investigations were carried out as wear experiments using a pin-on-disc tribometer in dry sliding circumstances at three distinct load (15N, 20N, 25N), sliding distance (1000m, 2000m, 3000m), and sliding velocity (2.5m/s, 4.5m/s, 6.5m/s). The significance of various strictures on wear analysis was investigated using Taguchi’s L27 orthogonal array approach. The findings of Taguchi’s and design of experiment show that the variables most likely to have an impact on wear loss is load, sliding distance, and sliding velocity. The composites bonding structure and wear surface were examined using an optical microscope and a field emission scanning electron microscope. The wear tests reveal that the treated Titanium alloy hybrid metal matrix composites with tungsten carbide and graphite particles have excellent wear qualities with a sliding velocity of 6.5 m/s and a load of up to 35 N in the region with the lowest wear loss of 0.039mm<sup>3</sup>/m. This study adds additional data to the dry slide wear resistance of composite consisting of Ti-6Al-4V alloy and reinforced through WCp with Grp, which are ideal for usage in automotive and transportation applications. The automotive industries employed dynamic conditions resulting in wear loss. To reduce wear and increase vehicle economy and performance, the tribological behavior was researched.</div></div>
