dc.description.abstractFor the purpose of studying the possibilities of increasing the wear resistance, specimens of three steels with 0.2%C, 0.46%C and 1%C were surface alloyed with reinforcement from overlapping pastes with green SiC hard particles with the granulation 800 and 320. The melting of surface layer was performed by CO2 continous wave laser on a numerical x-y table. On these specimens the micro structural characteristics, geometry of molten zone, micro hardness variation in the alloyed layer depth and the HV5 hardness on a laser processed surface were determined, which allowed defining the added material with the best hardening effect. The conditions to obtain compact surface layers with 2-3 time higher hardness than the base material were determined.ro_RO
