Abstract
Aluminium and its alloys (AA) are widely used in aerospace and automotive industries due to its superior properties such as stiffness to weight ratio and high strength. However, the less hardness and reduced wear resistance can limit their uses in several applications. In the present study, FeCrMoVC layers were formed on AA6061 material. Besides, the produced layers were investigated to reveal their new phase formation, hardness changes and microstructure. Sliding wear study was performed on both clad surface and base material. The wear mechanism and roughness average was evaluated and compared. The formed structure comprised of carbides and martensite with improved hardness. The wear resistance of the clad layer was improved 9 times better than base material. Abrasive, adhesive and delamination were the major wear mechanism on the base material while clad surface showed mild abrasive wear. The worn-out cladding surface showed three times lesser roughness while compared with base metal.
