Investigation of interphase interaction of ferrotitanium with silicon carbide in powder mixtures used for thermal spraying of coatings

摘要

Exothermal interaction in FeTiDSiC system was investigated. Maximum exothermal effect was achieved in use of 79 mass percent FeTi + 21 mass percent SiC mixture with the formation of TiC, Ti_5Si_(3-x)C_x, Fe_3Si, Fe_5Si_3 us products of interaction. The powder mixture of this composition is most challenging for producing composite powders and spraying of thermal coatings with a high wear- and corrosion resistance.
