Summary 1. It was established that skeletal carbide-graphite materials can be produced as a result of the sintering of compacted graphite powder during chemicothermal treatment with carbide-forming elements. The thickness of the component should not be more than twice the depth of carbide occurrence. 2. Kinetic curves of growth in the depth of carbide occurrence during chromizing have an inflection point, beyond which the rate of growth markedly decreases. This is due to the closing of pores from the direction of the specimen surface and cutting off of the supply of the active gaseous medium into the pores. The kinetics of growth in the depth of carbide layer are governed by the rate of sealing of pores, which depends on the process temperature, particle size of the graphite powder, and activity of the impregnating medium. 3. The use of a plasticizer (rubber solution in gasoline) has practically no effect on impregnation kinetics.
