Abstract

Multilayer cladding by injection of high-speed steel powder with 0.82%C, 4.7%Mo, 6.4%W, 4.1%Cr, 2.02%V, 0.3%Mn, as chemical composition, in melted bath by CO2 continuous wave laser connected to x-y-z coordinate table was tested in order to increase the wear resistance and heat proving of tool active surfaces made of 0.45%C steel. Layers made by different laser running were characterized by macro and microstructure analysis, as well as phase quality analysis by X ray diffractometry, microhardening analysis and hardness finding on coated layer surface in order to establish the optimal cladding run. Lathe tools made by this procedure showed a good behavior when steel shaping.
