Abstract
Thermal processes at forming a composite titanium carbide basis coating are investigated in work. The mathematical model of thermal processes at influence by a plasma impulse on the plaster con-taining SHS-reagents with initiation of the self-propagating high-temperature synthesis is developed. Boundary value problem was solved by finite volume method in two-dimensional statement with use of iterative processes. A series of numerical experiments on studying of behavior of initial charge at various processing of a sample is carried out. It is shown that a character of SHS significantly de-pends on the power of a plasma stream, a distance of processing, heating of a substrate, etc.
