Abstract

Paper presents the results of study of bimetallic zone of a high-temperature synthesis, which selfproparates (SHS), due to the temperature activation and structure of metal, influence of temperature of 473, 673, 873 K when using 40 % of metal powder filler. The optimal preheating temperature of the thermal charge for the production of a qualitative joining of the layers upon fusing is 873 K. The presence of finely dispersed refractory powders in a thermic alloy within thousandths and hundredths of a percent results in a sufficiently high increase in mechanical properties of parts. Inclusions of corundum serve as a modifying additive and centers of crystallization, having high sedimentation resistance, ensuring the formation of smaller crystals. The particles of corundum in the alloy can act as a seed for nucleation and growth in the microstructure of the primary carbides (Cr, Fe)7C3 with high-chromium wear-resistant cladding.
