Exploring the Wear Characteristics of Aluminum Matrix Composites

Abstract

This research assesses wear characteristics of an aluminum composite, in response to global demands for weight, cost, strength, quality, and productivity, materials have transitioned from refined forms to composite structures. The study examined stir casting of an Al-23wt.% Si alloy incorporating 2, 4, and 6 wt.% Al2O3, as well as 5, 10, and 15 wt.% SiC. The tribological characteristics of unreinforced alloys and composites were examined under dry sliding conditions and different loads using a pin-on-disc device, a standard L9 orthogonal array is utilized in these tests. The wear rate, SWR, and COF of aluminum composites can be analyzed by investigating influence of testing parameters. Minimizing wear on aluminum composite dry slides necessitates thorough testing under specific conditions, confirmation test compares experimental and forecast statistical results. Mechanical mixed-layer growth will be identified to determine the wear resistance of composites.
