Dry sliding wear response of aluminium matrix composites (AMCs): a critical review

Researchers were compelled to create composites as alternatives to the already used engineering materials due to the industrial desire for fresh, promising materials with superior mechanical and tribological properties. Due to their superior characteristics, aluminium matrix composites (AMCs) with the appropriate class of particulate/particle reinforcements have been shown to have a wide range of tribological applications. A thorough evaluation of the sliding wear response of aluminium matrix composites (AMCs) in a dry environment using a pin-on-disc wear tester has been attempted in this review study. A discussion regarding wear performance of Al monolithic alloy and its composites has been made with respect to varying process parameters (e.g. normal load, sliding distance, and speed) and the concentration of different particle reinforcements incorporated in the production of aluminium matrix composites. The existing paper provides a synergic presentation of the effects of various intrinsic and extrinsic variables on wear characteristics, leading to the novelty and uniqueness of this review article.
