“…Work hardening leads to a reduction of the contacting surfaces grinding against each other, thus reducing the friction coefficient. This may also be due to thicker oxide layer formation as the applied load increases, which leads to the reduction of asperities interaction between the contacting surfaces (Lakshmanan and Amith, 2020). Then when the applied load exceeds a critical value, the stability and integrity of the oxide layer are destroyed, result in the increase of friction coefficient.…”

“…Parts of the removed SiC particles are entrapped between contacting surfaces, possibly leading to three-body abrasion and result in higher values of the coefficient of friction (Mazahery and Shabani, 2013;Vencl et al, 2010). However, opposite result was obtained by Lakshmanan and Amith (2020). They reported that the decrease in coefficient of friction can be seen with increase in the SiC nanoparticles volume percentage in the matrix.…”

Purpose The purpose of this paper is to understand the effect of particle content, applied load and sliding speed on the tribological properties of A356-SiCP composites manufactured using a newly developed vacuum stir casting technique. Design/methodology/approach A356 alloy reinforced with 10, 15 and 20 vol% SiC particles was prepared by vacuum stir casting. Tribological tests were carried out on block-on-ring tribometer under dry sliding conditions, room temperature. Wear mechanism was investigated by scanning electron microscope and energy dispersion spectrum. Findings SiCP is homogeneously dispersed in the matrix. The increase in SiCP content decrease wear rate, but it leads to an increase in coefficient of friction. The wear rate increase and friction coefficient present different variation trends with increasing load. For A356-20%SiCP composite, when the load is less than 10 MPa, wear rate and friction coefficient under sliding speed of 400 rpm are lower than those of 200 rpm. Wear mechanism transition from abrasion, oxidation, delamination, adhesion to plastic flow as load and sliding speed increasing. Practical implications Results of this study will help guide the use of A356-SiCP in many automotive products such as brake rotors, brake pads, brake drums and pistons. Originality/value There are few paper studies the effect of particle content, applied load and sliding speed on the tribological properties of A356-SiCP composites. Aluminum matrix composites with uniform distribution of reinforcing particles were successfully prepared by using the newly developed vacuum stir casting technique.

“…Figure 6(a) to (c) show the different schematics of the casting process which have been combined with ultrasonic vibration setup. 34,38,48 From the literature survey, it has been observed that many studies reported the use of ultrasonic vibration in the casting process but hitherto little has been reported on a novel setup of casting which combines the sandcasting technique with ultrasonic assistance. Hence in the future researchers can work on assisting the sandcasting process with ultrasonic vibrations to study the effect of ultrasonic vibrations on the sand as well as on the cast properties.…”

“…Whereas the nano SiC particle reinforced MMC had shown better wear properties compared to the monolithic Al alloy cast. 48 One of the studies reported the use of high-energy ball milling (HBM) for crushing the SiC particle up to 1.5-2 mm and the particle obtained through HBM were melted with Al matrix-assisted with ultrasonic vibrations. The study reported that 1wt% reinforcement of SiC particles in the Al matrix leads to a 19% increase in mechanical performance, especially tensile strength.…”

Conventional manufacturing processes such as casting, forming, welding, machining, etc., have been optimized using different improvement techniques in the last few decades. The alterations in these processes have led to more efficient and productive manufacturing practices for the industry. One of these modification techniques is the deployment of ultrasonic vibrations in conventional manufacturing processes. In the last few decades, ultrasonic vibration assistance to manufacturing processes has seen an uprise and was the point of attraction for different research groups. Several improvements by utilizing ultrasonic vibration in manufacturing practices have been reported by the authors in the past. In this article, an attempt has been made to review all the reported techniques for different conventional processes viz. casting, forming, machining, and welding. The article outlines different research findings from the extensive work on ultrasonic vibration assistance showcasing the improved mechanical and morphological properties. The improvisation in the performance parameters viz. friction reduction, stress reduction, tool wear, surface finish, and grain structure has been witnessed by ultrasonic assistance in contrast to simple manufacturing processes. The outcomes have been summarized along with the optimized set of parameters from various studies.
