| Abstract | In order to obtain surfaces with various tribological properties, two pastes having various concentrations of Ni, Cu, Al, Ti, Cr and Fe were predeposited on specimens of 1C35 steel grade. The specimens were processed with multiple passes on the numerically controlled x-y-z table at the rate v = 10 mm/s and the overlapping degree s = 35%. The simultaneous melting of added material and surface layer was performed by a CO2 continuous wave laser with the 1300 W power beam and the 1.2 mm diameter beam, under argon protection. The surface layers were analyzed by means of diffractometry, spectral analysis, metallographic analysis, microhardness and load carrying capacity measurements. |
