Promising improved mechanical, wear, corrosive properties by the impact of CNTs on Al alloy by FSP – A review

Abstract

The monolithic alloys of aluminium have the qualities of less density, elevated strength and high resistance to corrosion. Generally, alloys of aluminium are most comprehensively used in the fields of aerospace sectors such as skeleton parts of aircraft, fuselages, bulk heads, wing ribs, wing spars, automobile and transportation industries, architectural parts, electrical and electronic applications, etc.The evolution of microstructure, and mechanical characteristics such aselongation, hardness, tensile strength, tribological property, and corrosion resistance are examined in this paper for the composites of aluminium-carbon nano-tubes (CNTs). With the use of a surface composite processing method known as friction stir processing, CNTs are added as reinforcements to improve the various properties of the base metal. The CNTs provide a wide variety of characteristics, such as outstanding electrical conductivity, thermal stability, high strength, and superior elastic properties.Numerous collections of published literature have been thoroughly studied, and it discusses a few of the essential underlying assumptions needed to achieve the optimal combination of CNTs with the aluminium under friction processing technique. From the comprehensive review, the statements are summarized that will assist future research work involving the accumulation of CNTs reinforced with aluminium alloy and utilized in various applications of aerospace and aircraft sectors.
