Abstract
The processes occurring during the formation of multicomponent diffusion coatings on nickel alloys at the stage of delivery of elements on the article surface when chlorine, bromine, and iodine halides are used as activators are considered. Balance equations and calculated values are given for the partial pressures in the composition of a gas phase of components participating in chemical transport reaction; the possible reactions of delivering elements on the article surfaces and the structures of Ni–Al, Ni–Cr, Ni–Cr–Al, Co–Cr–Al coatings deposited on the ZhS26, ZhS6U, ZhS32, and VZhL12U alloys are presented.
