Conclusions
-
1.
An examination is made of the mechanisms involved in the reactions occurring on the surfaces of carbonaceous substances and metals being impregnated, during carbidization from a solid-phase bath in a hydrogen atmosphere. It is shown that the rate of formation of atomic carbon on a metallic surface depends upon the reactivity of the metal, the nature of the hydrocarbons being adsorbed, and the process temperature.
-
2.
The effects are considered of structural heterogeneities and common impurities upon the processes of formation of hydrocarbons and the character of their reactions with metals.
