“…The results obtained are similar with those obtained by Lee et al. 23 who have reported that the wear mechanisms are strongly dependent upon the sliding speeds. At low speed, the wear rate is lower since the damage caused to the tribolayer formed between the mating surfaces is less, while under high speeds, there is a breakdown of the tribolayer leading to excessive wear.…”

The dry sliding wear behaviour of LM 24 aluminum alloy composites reinforced with garnet particles was evaluated. Stir casting technique was used to fabricate the composites. A pin-on-disc wear-testing machine was used to evaluate the wear rate, in which an EN 24 steel disc was used as the counterface. Results indicated that the wear rates of the composites were lower than that of the matrix alloy and further decreased with the increase in garnet content. However, in both unreinforced and reinforced composites, the wear rate increased with the increase in load and the sliding speed. Increase in the applied load increased the wear severity by changing the wear mechanism from abrasion to particle cracking-induced delamination wear. It was found that with the increase in garnet content, the wear resistance increased monotonically. The observations have been explained using scanning electron microscopy analysis of the worn surfaces and the subsurface of the composites. In this work, the most influencing input and output parameters have been performed and the process parameters have been prioritized using genetic algorithm. Genetic algorithm is used to optimize the most influencing input as well as output process parameters. The practical significance of applying genetic algorithm to dry sliding wear behavior process has been validated by means of computing the deviation between predicted and experimentally obtained wear behavior of metal matrix composite.

Aluminum metal matrix composites have found applications in manufacturing of various components such as piston, cylinder block, and brake drum, in which wear and friction are important phenomenon. This paper presents an overview of diversified reinforcement on aluminum metal matrix composites in terms of tribological aspects. A comprehensive literature review is carried out on aluminum metal matrix composites based on individual reinforcement and multiple reinforcements including various product applications. The research review is summarized in form of tribology wheel for aluminum metal matrix composites, which encompass fields involved in tribology, fabrication processes/parameters, reinforcement(s) and matrix contribution, tribological testing parameter, statistical analytical technique, and product application areas of AMCs. The tribology wheel becomes helpful in selecting parameters with possible permutation and combination for further improvement of tribological properties. Finally, comments are addressed regarding the future work on tribological aspects of aluminum metal matrix composites.

“…Tool rotational speed is the most important process parameter in FSP which has greater influence in uniform distribution of reinforcement particles, grain refinement and heat input during the process. Many researchers have given their valuable contributions in preparing surface composites by the use of FSP technique with various reinforcement particles like SiC, Al 2 O 3 , Al 3 Ti on the surface of Aluminum alloy 6061-T6 [7][8][9][10]. MMCs prepared by addition of single or mixture of two or more different types of particles with certain volume fractions into the parent alloy.…”
