Abstract
To increase resistance to wear of the surface layers made from 0.45% C steel, a multilayer deposit by powder injection with the chemical composition Cr 8.9%, 4.5% Fe, 5.1% B, 2, 4% Al, 0.6% Cu, and Ni was tested in a molten bath with a continuous wave of CO2 laser, coupled to a table within x-y-z coordinates. The layers were characterized by microstructural analysis, qualitative analysis of phase with the radiation difractometry X and EDX microanalysis. It was determined the friction coefficient developed during sliding indentation in dry friction conditions.
