Effect of Laser Cladding Al₃Ti-Based Coatings on the Wear and Corrosion Resistances of AA6063 Aluminum Alloy

Abstract:

Al3Ti-based intermetallic compound coatings were formed on AA6063 aluminum alloy by laser cladding. The microstructure, wear and corrosion behaviors were investigated. The results showed that, the laser cladding coatings were made up of Al3Ti dendrites, interdendritic α-Al and uniform distribution of TiC particles, and showed good bonding to the substrate. The microhardness, wear and corrosion resistances of the laser cladding coatings greatly increased compared to the substrate. And with the addition of TiC particles to the coating, the superficial properties are improved simultaneously.
