Influence of laser alloying on structure, and microhardness of surface layers was investigated. Alloying depended on laser re-melting of 41Cr4 steel's surface layer with coated paste containing amorphous boron. In order to produce those layers, the technological laser TRUMPF TLF 2600 Turbo CO2 of the nominal power 2.6 kW was applied. Boriding was carried out with laser power P=0.91 kW, P=1.3 kW and...
