Microstructure and Tensile Properties of Nickel-aluminum Bronze Coatings on Stainless Steel SUS630

Abstract:

Nickel-aluminum bronze coatings were deposited on high strength stainless steel SUS630 by laser cladding. The microstructure of the multi-layer structures was investigated. The OM results showed that steel-bronze bimetallic materials were successfully fabricated without any defects. The dilution rate of substrate can be adjusted by controlling the laser parameters. The main phases of the coating are α-Cu, Fe-rich dendrites and κ phases. Tensile tests were carried out and it was found that the upper specimen with fewer Fe-rich related components had better tensile strength properties.
