Conclusions
As a result of an investigation, into the high-temperature solid-phase reaction of boron carbide with titanium under ordinary and plasma heating conditions, it has been established that the reaction, which begins at 1300°C, is slow in its final stage, which is due to the appearance of a zone of porosity and to disturbed contact between the reactants. Because of this, in spite of its being accompanied by an appreciable thermal effect, the reaction fails to proceed to completion under conditions of both continual ordinary heating (to 1600°C) and plasma heating. It is possible to obtain spray-deposited coatings of the required composition (TiC+TiB2) by employing preconglomerated or clad Ti -B4C powders and preheated basis plates.
