Investigation of interphase interaction of ferrotitanium with boron carbide in powder mixtures for thermal coating deposition

摘要

Interaction of ferrotitanium with boron carbide, which is accompanied by a significant exothermal effect, is investigated. It was established that the maximum exothermal effect is attained at ferrotitanium interaction with boron carbide in powder mixture of the following composition: 85 mass percent FeTi + 15 mass percent B_4C with the formation of reaction products TiB_2, TiC, Fe_2B, Fe_3b, Fe_3C. This powder mixture is the promising material for coating deposition using the methods of thermal spraying.
