An investigation was made on the effect of the conditions of boration and carbidization of titanium, zirconium, niobium, tantalum, molybdenum, and tungsten on the structure, phase composition, and thickness of diffusive carbide and boride coatings. The parameters of the diffusion of boron and carbon in the enumerated metals are determined by the results of metailographic, x-ray, and chemical investigations, as well as measurements of the thickness and microhardness of the diffusion layers. The previously established dependence between the criterion of acceptor capacity of the d-electron shell of methl atoms 1/N n (n is the number of electrons on the d-shell, N is the principal quartum number) and the magnitude of energy activation is confirmed.
