Abstract

Способ получения термоустойчивых покрытий, включающий формирование на подложке многослойной структуры, состоящей из последовательно нанесенных слоев: слоя металла, в качестве которого используется железо, никель или кобальт, и слоев хрома, алюминия и иттрия, полирование структуры, нанесение слоя керамики столбчатой структуры и термообработку покрытия в кислородсодержащей среде, отличающийся тем, что, с целью повышения долговечности покрытия, нанесение слоя керамики осуществляют толщиной, сохраняющей сквозную пористость, после чего проводят нагрев подложки в вакууме до плавления легкоплавкой составляющей многослойной структуры с последующим нанесением слоя керамики до заданной толщины.The method of obtaining heat-resistant coatings, including the formation on the substrate of a multilayer structure consisting of successively applied layers: a metal layer, which uses iron, nickel or cobalt, and layers of chromium, aluminum and yttrium, polishing the structure, applying a layer of ceramic columnar structure and heat treatment of the coating in an oxygen-containing environment, characterized in that, in order to increase the durability of the coating, the application of a layer of ceramics is carried out with a thickness that maintains through porosity, after which oestriasis substrate heating in vacuum to melt fusible component multilayer structure followed by application of the ceramic layer to a predetermined thickness.
