摘要：
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 gasturbine blades, which, at working temperatures, prevent the formation of undesired topologically closepacked phases in a protected heatresistant nickel alloy and its coating for a given lifetime. © 2013 Pleiades Publishing, Ltd.
