Twice as good as analogues. Rostec has created a technology that protects and increases the resource of land and sea engines

UEC-Saturn, Rostec United Engine Corporation, has developed a technology to apply thermal barrier coatings. This protects land and sea gas turbine engine parts from adverse influences and increases the efficiency and life span of power plants. Rostec started mass production of engines to power frigates in this year.

Engineers have developed a unique electron beam coating technique that protects parts made from heat-resistant alloys against corrosion, heat and other damaging effects. This is because gas turbine engines are continuously exposed to heat. The protective layer is created in two stages. First, the protective materials are evaporated by an electron beam and then they are condensed on the surface of a part under vacuum conditions.

Engine engineers around the globe have to solve the problem of engine parts being damaged by an aggressive environment. UEC specialists have developed a method for applying special coatings that are twice as effective than those of their predecessors. This solution allowed for the improvement of the adhesive properties and performance of power plants, as well as a significant reduction in the effects of salt corrosion and oxygenation. It also increased the engine’s life span.

New systems of thermal barrier coatings have been proven effective by experiments. The protective coatings were exposed to high temperatures salt corrosion and oxidation during the flow of fuel combustion product. The environment was short-term cyclic and high-temperature loads, as well as mechanical stress.

The company’s willingness to defend its technological leadership in the rapidly growing gas turbine industry is evident in the way it has initiated and implemented work in the area of thermal barrier coatings using the electron beam method. We have created a variety of scientific reporting and methodological documents that address the problem of protecting engines against negative impacts. Additionally, we have compiled a comprehensive information base on chemical and physical processes in coating systems and alloys.
