Abstract: The increase of thickness of carbide layer during carbide diffusion coating is proportional to the root of carbon activity in various steels. Thus it was demonstrated that the controlling fac- tor of the dynamics of carbide layer growth is carbon activity in steel matrix, but not carbon concentration.

Key words: activity of carbon, carbide diffusion coating, steel
