Definitions
- the invention is not available in the area of metallurgy or machinery; and. in the area. the engine and engine parts of the gas turbines of aircraft engines.
- the blades of the turbine are made from available hot alloys based on nickel. flavors and iron. with a very complicated technology of production. for example, by way of direct installation or multiple casting. Therefore, their cost is extremely high. It is clear that the technology for applying protective ac- tions to such parts has a greater economic and technical value.

In this case, too, protection is only necessary for external disturbances and high adhesion to the substrate is not ensured. 4
- the bulk of the invention is dedicated to long-term reliability and reliability of high-temperature protective products for hot metal alloys. in particular, for the blades of turbines of aircraft engines. 5
- intermetallic layers serve as suppliers of components to the outdoor area for restoring acid phase.
- for example, aluminum and at the same time, diffusion of elements inside the interior is avoided.
- Barrier functions also carry mixtures from the large phase.
- Another example is related to the multi-component alloy of the S ⁇ - ⁇ -Sg- ⁇ - system

- ⁇ has a high flexibility. including ⁇ and thermocyclic loads. and the required thermal expansion factor, which increases the speed of the contact with the oxidized layers to the thermal fatigue.
- the thickness of the industry in the industrial area is subject to the conditions of operation and is subject to change between 10-300 microns and the area of the region of 200 to 200
- the microbial industry may be supplied up to 3 to 300. Between the microbial industry, diffuse zones may be used, as is the case during the process of application of the process, or
- a small component may be a discrete layer that is different from the basic material, or another mixture that has been applied, or may be mixed with it.
- Intermetallic mixtures of (II) are composed of the following phases Phase 2 ( ⁇ ) and (Phase) 3 Phase 2 ( ⁇ ) and phase transition ( ⁇ ).
- ⁇ kann ⁇ is nickel. Calcium, iron, He; - aluminum, titanium, chrome, and other elements. They are applied to the main hot alloy on the basis of iron. nickel or paint or in the middle of the event. obtained by ion-plasma deposition, electron-beam technology, or implantation, with the use of process of diffuse non-metallic, inert gas, inert gas,

- the payment of the benefits of the payment does not involve the payment of the payment process and the foreign payment, but also the payment of the payment of the remuneration.
- the inventive event is from an intermetallic layer.
- Such protective protective devices for gas turbine blades of aircraft engines from hot alloys on a nickel base for example, ZhS6 ⁇ .
- ZhS6U provides I protect the outside of the blade> the blade and the internal air of the coolant due to the application of lightweight aluminum oxide through gas phase pulsed gas.
- a more recent application of the current application is the large-scale protective cover, including the inclusion of a non-metallic alloy, which is not
- the foreign-applied metal method from the group was applied by the foreign-plasma method.

Abstract
L'invention relève de la métallurgie et des constructions mécaniques et concerne le développement de revêtements de protection destinés à des pièces en alliages réfractaires et notamment aux ailettes de turbines. L'invention consiste à appliquer aux pièces des revêtements de protection ayant des propriétés réfractaires élevées, une bonne résistance à la corrosion dans les produits de combustion du carburant et une meilleure résistance aux cycles thermiques. Le revêtement est constitué de microcouches dont la combinaison confère des propriétés d'exploitation élevées aux composés intermétalliques, métaux et alliages condensés, oxydes et microcouches de transition obtenues par des procédés d'implantation d'ions. Ces revêtements et leur traitement par des flux d'ions à énergie élevée permettent un degré élevé d'adhésion à la surface de base et entre les microcouches, une répartition favorables des contraintes intérieures et l'apparition de nouvelles phases et structures dans le revêtement. Cette invention permet d'augmenter l'endurance et la durée de vie de pièces telles que notamment les ailettes de turbines à gaz et tout particulièrement des ailettes de turbines de moteurs d'aéronefs.
