Development of Theoretical Foundations of the Controlled Synthesis of Multifunctional Coatings by the Micro-$rc Oxidation Method

A methodology for the controlled synthesis of protective coatings by the micro-arc oxidation method, including a mathematical model of a galvanic cell based on an equivalent electrical circuit, as well as a model of the interconnections between the technological parameters of the micro-arc oxidation (MAO) process and the properties of the obtained oxide layers based on graph theory has been developed. The indicated dependences are formalized using methods of regression and correlation analysis of experimental data. A technique for the controlled synthesis of MAO coatings using the obtained regression equations is proposed. The technique was used in the selection of optimal technological parameters for producing oxide layers with a thickness of $100 \mu\mathrm{m}$ and a minimum porosity. A prototype of an intelligent automated system for the controlled synthesis of MAO coatings, which was used to obtain experimental dependences of reaction parameters on the influence parameters of the micro-arc oxidation process was created; the principle of the hardware and software of the system is presented.
