Laser Deposition of Bronze Aluminum on Steel Support
Keywords:
laser cladding, aluminum bronzes, microstructure, microhardness, diffractometry
Abstract
In order to rise the wear and corrosion resistance of 0.45% C superficial steel layers, a multilayer coating was tested by injection of powder with 88.3% Cu; 9.5% Al; 2.2% Fe in melted bath by CO2 continuous wave laser. Layers made by different laser conditions were characterized by macro and microstructure analysis, phase quality analysis, by X ray diffractometry and microhardness analysis. Research was carried out regarding the importance of nickel alloy intermediary layer for the rising of cladding quality.
