A Review on Abrasive Wear of Aluminum Composites: Mechanisms and Influencing Factors

Abstract

Aluminum matrix composites (AMCs) find extensive use across diverse industries such as automotive, aerospace, marine, and electronics, owing to their remarkable strength-to-weight ratio, corrosion resistance, and mechanical properties. However, their limited wear resistance poses a challenge for applications requiring high tribological performance. Abrasive wear emerges as the predominant form of wear encountered by AMCs in various industrial settings, prompting significant research efforts aimed at enhancing their wear resistance. Over the past decades, extensive research has investigated the influence of various reinforcements on the abrasive wear behavior of AMCs. This paper presents a comprehensive review of the impact of different variables on the wear and tribological response of aluminum composites. This review explores possible wear mechanisms across various tribosystems, providing examples drawn from the analysis of existing literature. Through detailed discussions on the effects of each variable, conclusions are drawn to offer insights into optimizing the wear performance of AMCs.

Enhanced mechanical and tribological properties of ultrasonically assisted stir-cast AA7075 metal matrix composites in challenging corrosive environments

“…Significant material deformation, adhesion, and abrasion were observed due to the interaction of a high AL (20 N), moderate SV (0.4 m s −1 ), and an extended SD (2000 m), resulting in increased wear loss. The decreased sliding velocity was insufficient to offset the wear under these conditions [51]. The AA7075/15 wt%WC composite demonstrated lower wear rate under an AL of 20 N, a SV of 1.2 m s −1 , and a SD of 1000 m. Increasing the SD in all cases led to higher wear loss, while increasing the sliding velocity reduced wear loss.…”
