Effect of process factors and chemical composition of steels on the structure and properties of nickel-bearing diffusion coatings

The effect of the medium and regime of saturation and of the composition of the steel on the composition, structure, and properties of nickel, nickel-copper, and nickel-chromium diffusion coatings formed by selective transfer of the elements of the coating in a medium of low-melting liquid-metal solution is considered. The regular features of formation of nickel-bearing diffusion coatings on various steels are determined, which makes it possible to control the saturation process and form coatings with specified composition, structure, and properties. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 4, pp. 38–43, April, 2007.
