Review of aluminium composites and their tribological and mechanical properties
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 7
Abstract
Aluminium metal matrix composites (MMC’s) play a crucial role in various fields like automobile, aerospace, military, aircrafts, sheet metal, construction etc. due to unique combination of their properties. The properties such as high strength to weight ratio, high wear resistance and low cost lead to increase in the demand of aluminium composites. Various fabrication techniques are available to produce such composites. In liquid phase processes, Stir casting is a widely used process to fabricate aluminium composites. This paper reviews the effects of various reinforcements on tribological and mechanical properties of aluminium alloy. Various reinforcements like SiC, Al2O3, TiC, MoS2 etc. are used to produce composites. We can fabricate a composite material with the single reinforcement or the combination of two or more reinforcements depending upon the application. Other than that we can also use coatings of alumina, calcia-stabilized zirconia coatings, plasma electrolyte oxidation layers etc. to get better surface properties of aluminum alloy. These coatings are widely used where continuous rubbing motion is desired between two surfaces.
