- establishing the types of powders to be used and the substrate on which the deposit will be made;
- choosing the optimal technological parameters for performing plasma jet spraying;
- making the coatings and analysing their characteristics;
- testing the coatings obtained for specific demands of turbine blades in operation (thermal shock testing, microstructural and chemical evaluation, corrosion, differential mechanical properties analysis, etc.) and evaluating the results obtained;
- validation of the results by comparing the results obtained with those from the literature.

8. Objectives
 

This research aims to investigate the thermos-physical properties of a layer sprayed in a plasma jet at normal pressure. The research focuses on the changes that occur following the exposure to high temperatures from both a microstructural, stiffness and thermal points of view. Thermal barrier vane coatings (TBCs) are used to insulate gas turbine components that are subjected to severe temperature regimes, thus ensuring their proper operation that would otherwise not be possible due to excessive heating of the base material from which they are manufactured. TBC type layers allow the temperature of "hot parts" targeted in the energy  industry, aeronautics, etc. to decrease by 100–200° C. The intended thermal barrier effect allows the temperature and efficiency of the turbo engines to increase. Making ceramic coatings on the vanes of gas turbine engines for aviation is currently a common method for increasing the resistance and durability of the vanes. Considering the detailed presentations from the current stage of research in the field, it was found that plasma jet spraying is one of the most modern and efficient deposition processes. The development of research in this field is channeled in two major directions:

-the discovery of new types of multilayer structures used based on the selected powders, by depositing which to obtain layers with the necessary properties;

-modeling the technological parameters of the deposition process to improve the characteristics of the deposited layers
