Paper Abstract

Material surface modification was carried out by laser alloying technology with an additional material. The final effects are based on micro-structural changes in the surface layer, furthermore by changing the material composition in the surface. Sic powder was applied on CSN 41 20 10 steel into melting pool generated by interaction with the moving C02 laser beam. Numerical modelling of the temperature field on the substrate appears like a good way to optimalization of process parameters. The final surface structures are presented and analysed by scanning electron microscopy. The microhardness of treated layers in comparison with substrate is described too.
