Pidkova V. Increasing performance properties of the heating elements by synthesizing nanostructured functionally graded layers

The object of research is processes of structure formation of the dielectric layers during formation of the oxides and nitrides Mg, Al, Ti by surface engineering methods. The aim of the work is establishment features of structure formation of the functionally graded dielectric layers with oxides and nitrides of Mg, Al, Ti for increasing the performance properties of film heating elements. The characteristics of structure, the nature of the defect distribution of the crystal structure and phase composition of the dielectric layers of MgO, TiO2, Al2O3, AlN lined 40X13 steel, alloy AMg2 depending on the mode of their formation were studied at work. As a tool for the creation of such layers justified the feasibility of using one of the methods of surface engineering - ion-plasma sputtering. The correlation between the chemical composition of the dielectric layers of the structure, their adhesion to the surface micromechanical, thermal and physical properties were found. A series of comparative experiments established the optimal combination in the system "substrate - dielectric layer" - "Steel 40X13 - AlN". In the studied systems, the optimal modes of applying dielectric layers which provide structural formation geometry and phase composition to achieve the required performance properties were found. To manage application modes and quality control of dielectric layers (the parameters of the microstructure, the level of defects, adhesion and electrical properties) first configured and customized software neural network fuzzy logic controller T - Controller Workshop and developed a software neural network predictor "DB/Gradient 1.1". Based on the research developed a prototype that entered the construction heater KEP 2-10-4-220/380 and successfully passed the test bench on OOO PKPP "Kreduv."
