Abstract :
Paper presents fundamental problems of surface ceramic layers after homologitation by laser beam. Paper deals with study of microstructure, hardness of coating WC - Co alloyed by laser Nd:YAG. Samples were machined by laser of different outputs, where samples were compared of their hardness and structure. Paper also comparing coating and its characteristic in different conditions and final proposal of workplace focused on the highest efficiency.
