550^oC temperature hot rolled tape is lined up on winding reel by some manipulators having the wearing plates in touch with moving tape edge. Quick abrasion and oxidation wearing of these plates result. In order to enlarge their useful life, it is requested the coating of a superficial layer of material with higher wear and oxidation resistance.

Multilayer coating by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B, 2.4% Al, 0.6% Cu, all reminded of Ni, as chemical composition, in melted bath by CO₂ continuous wave laser connected to x-y-z coordinate table was tested in order to rise the wear and corrosion resistance of 0.45% C superficial steel layers. Layers made by different laser running were characterized by macro and microstructure analysis, as well as phase quality analysis by X ray diffractometry and micro-hardness analysis in order to establish the optimal deposit running. Optimal nickel alloy coating running achieved a 2 mm in depth dense layer with HV_0.98 micro-hardness varying between 9543MPa and 12640MPa. Optimal running was used in order to get the wearing plates of winding system manipulators of hot rolled stripes.
