Complex determination of the diffusion coefficients of alloying elements in heat-resistant nickel alloys and deposition of multifunctional multilayer protective coatings

We showed the possibility and suggested the calculation procedure of determining the diffusion coefficients of elements in complex doped alloys from the distribution of elements in dendritic cells of heat-resistant nickel cast alloys. We developed a new technology to deposit multifunctional coatings on gas-turbine blades, which, at working temperatures, prevent the formation of undesired topologically close-packed phases in a protected heat-resistant nickel alloy and its coating for a given lifetime.
