The work represents the results of the experiments associated with the development of a fundamentally new composite intermetallic ceramic coating for hot section parts of gas turbine engines. It was determined that the combination of arc-jet and magnetron methods gives opportunity to expand the scope of sputtering when creating heat-resistant coatings in vacuum. In such a way obtained coatings differs by the absence of a “drop” phase and, subsequently, by higher thickness and smoothness. In such a case, the best coating properties can be achieved by separate gas feeding into working chamber.
