The laser technology of the fusion of the working surface of details changes the surface properties, decreasing the microroughness of the processing surface, increasing wear resistance and microhardness. This work is intended for analyzing the differences in technological processes of fusion, alloying and the synthesis of material. Synthesis of material, fusion, and introduction into the matrix they were carried out using different compositions of powders under the action of laser emission. Investigated the minimum power density of laser emission for the melting of the covering is established its dependence on the chemical composition of coating and base of material. Evaluated the dependence of the temperature distribution in basis and coverage of layer on the thermal parameters of the basis of material and power of laser radiation.
