EDX Analysis of Laser Cladding Layers With Ni – Cr – B – Fe – Al Alloy
Abstract
Multilayer cladding by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B, 2.4% Al, 0.6% Cu, Ni rest as chemical composition, in melted bath by a continuous wave CO2laser connected to x-y-z coordinate table was tested in order to increase the wear and corrosion resistance of 0.45% C superficial steel layers. Layers made by different laser running were characterized by microstructure analysis, microhardness analysis and EDS microanalysis in order to establish the optimal deposit running.
