Wear characteristics of aluminium matrix nanocomposites (AMNCs) – A review

Abstract

Aluminium matrix nanocomposites (AMNCs) have the ability to meet the needs of innovative applications of engineering materials. These materials are on expanding utilization in industries like ground transportation, aeronautical, sports, and foundation due to the enhanced properties, for example, high strength to weight ratio, corrosion, fatigue, and wear resistance. A few applications including dynamic contact stresses require incredible wear and frictional execution for an improved life. In any case, the integration of these nanoparticles can diminish the wear execution of AMNCs under serious conditions. In several laboratory studies carried out so far in the most recent decade, it has been identified that the wear properties of Aluminium (Al) based nanocomposites are much better than micro composites and its alloys. Within this paper, the publication findings from the year 2016 to 2020 are focussed on the nano-sized reinforcements to analyse the wear performance which is affected by extrinsic variables such as loads, sliding speeds, sliding distance along with intrinsic aspects as microstructure and production method of AMNCs. The reviewed literature found that nano-particle reinforcements substantially enhanced the wear of Al and its alloy nanocomposites.
