Project summary

Summary of the Objectives of the Project, the Technical Approach and the Anticipated Results:

Purpose of Project to use an experience in the implantation-plasma technology, as a result of realizing the our ISTC 032-Project, for enhancing the cyclic strength and the resistance to the dust erosion of compressor blades.

It is expected to develop the implantation-plasma techniques for improving adhesion to the protective turbine blade coatings made of the inconel, MeCrAlY-type, and to other machine parts operating under sign-alternating loadings at high temperatures; corrosion-resistant coatings, MeCrAlY-type, by production of a layer, barrier-type, at the metal-coating interface in order to reduce the thickness of a transitional oxide layer; fatigue properties of the turbine blades and of other machine parts with protective coatings operating under sign-alternating loadings in an oxidizing-high temperature-medium, and to provide the conditions for reducing the oxide layer growth rate on the coating surface under high temperature oxidation.

Technical Approach:

For achieving the Project purposes both the results of the results of the developments done according to 032-Project, concerning the implantational technology modification and an experience, in realization of the coatings, MeCrAlY-type, by scientists and engineers from UEBPC and from USATU will be used.

In that case, the unique equipment at the RRC “Kurchatov Institute” will be used for performing the implantation and plasma treatments to clean the surfaces, as well as other facilities at the disposal of UEBPC and USATU for performing the coatings.

Expected Results:

The Project possesses of a great commercial potential, since its results can be spread in Russia, CIS and in other countries to the industrial enterprises on production and application of gas turbine blades, as well as for other products of work with complicated profiles, operating for a long time under sign-alternating loadings at high temperatures in an oxidizing medium.

The service life rise of the turbine blades is expected in a 2-3 times, in comparison with the traditional technology.

Potential Role of Foreign Collaborators:

The role of our colaborators will consists in the together study of irradiated samples, discussion of the obtained results and joint seminars.

Title of Project, its purposes, Program of studies including joint studies and also tests were consiliated with collaborator of Project from Karlsruhe.
