“…During application, the silicon carbide particles projected into the composite were in attached with the work surface throughout the test. Surface roughness of the sliding-pin was found because due to continuous contact with the disc surface which discovered the dis-turbed grain structures inside the sample at specific load and speed [22][23]. The silicon carbide-particles are very strong enough as compression to friction because during disc spin, instead of cracking the silicon carbide particles, the soft aluminum particles erode easily in the composite.…”

Metal-matrix aluminium composites are satisfactory successor not only for steels, but also for aluminium-alloys in several automotive units and components. There are various paths to get lightweight materials without compromising their toughness, strength and safety demands. Tests on dry-sliding or un-lubricated pin-ondisc tests can be performed to obtain the wear-characteristics of metal-matrix composites built on aluminum. In the present study, we studied the behavior of wear resistance during sliding of metal matrix aluminium composites (AMMC) at sliding speeds of 1.5 m/s and loads of 20 N and 40 N in a normal environment, and experiments have been conducted using pin-on-disk tribometer (Make: DU-COM tribometer). The composites were manufactured by powder treatment and presented a number of problems, such as defective bonds and inter-facial product reactions, which alter the tribological and mechanical properties. The results have shown that wear-rates of the prepared composites are much lesser than those of matrix-alloy and decreased further with increasing silicon carbide content. As the normal loads increases, the cracks and combination of abrasions, delimitation and wear of the adhesives of silicon carbide particles were observed. The composite samples were studied using a scanning electron microscope before and after the wear tests and systematically analysed.

“…The AA6061 matrix composites with ceramic reinforced (alumina, boron-carbide, and silicon-carbide) would enhance the resistance to wear in the hot-pressing process. The WR and volume-loss increase with increasing sliding distance and normal load [26], and the rate of wear decreases linearly as compared to increasing wt% of SiC and COF decreases linearly with increasing normal-load and wt% of SiC [27]. The wear and COF characteristics of the Al-SiC-MWCNT composite were greatly influenced by load and had a negative impact on the wear when the load was critical, and the hardness of the matrix composite was increased with increasing reinforcement percent [28].…”

There is a growing attention among researchers to the production of new composites with low-density and low-cost processes. Aluminum based metal-matrix composites (AMMC) offer solutions for new product development. In this paper, a newly developed Al-Mg-Si-Cu-SiC composite was manufactured by powder-metallurgy, and the wear mechanism of aluminum composite materials was carried out using the pin-on-disk method. The purpose of the experimental plan was to correlate the factors that influenced the wear operations in order to execute them with a minimal rate of wear and co-efficient of friction (COF). The experiment was based on the Taguchi design with OA (orthogonal arrays) to correspond to the effects of load applied, sliding speed, and distance. The design features are distinctive and integral attributes of the method, affecting and determining the wear characteristics of composites.The predictive models developed for various machining performance characteristics employing response surface methodology are effective in terms of adequate, statistically significant, and probabilistically validate because of their higher R2-values, P-values less than 0.05 and larger AD-test p-values. The data generated for the Al-Mg-Si-Cu-SiC AMMC will be useful for the industry. HIGHLIGHTS Preparation of AMMC through powder metallurgy method The WR decreases with the rise in wt% of SiC reinforced particles Taguchi orthogonal design model is best suited to examine dry sliding wear characteristics of an Al-0.5Si-0.5Mg-2.5Cu-10SiC composite Using the Taguchi-optimization method, it is more expedient to obtain the minimum WR of the composites GRAPHICAL ABSTRACT

“…Tool wear mechanisms can be studied under lab conditions using Pin-on-Disk or Pin-on-Flat tests [ 7 , 8 , 9 , 10 ] reducing the material cost and improving the environmental sustainability of the process. However, only a few studies have been found which investigate the specific tribological pairing of aluminum and tungsten carbide [ 11 ].…”

One of the main criteria for the establishment of the performance of a forming process by material removal is based on cutting tool wear. Wear is usually caused by different mechanisms, however, only one is usually considered as predominant or the controller of the process. This experimental research is focused on the application of Pin-on-Disc wear tests, in which the tribological interference between UNS A92024-T3 Aluminum–Copper alloy and tungsten carbide (WC–Co) has been studied. The main objective of this study is focused on the determination of the predominant wear mechanisms involved in the process, as well as the characterization of the sliding and friction effects by using SEM and Energy Dispersion Spectroscopy (EDS) techniques, as applied to WC–Co (cutting tool material)/Al (workpiece material) which are widely used in the aerospace industry. Performed analysis prove the appearance of abrasive wear mechanisms prior to adhesion. This fact promotes adhesion mechanisms in several stages because of the surface quality deterioration, presenting different alloy composition in the form of a Built-Up Layer (BUL)/Built-Up Edge (BUE).
