| Abstract |
Background. Microarc oxidation (MAO) is a promising way to obtain durable oxide coatings by means of plasma-chemical processing of parts from valve metals and alloys. To date, this process has limited application due to the lack of a systemic description of the relationship between technological parameters and properties of coatings. The aim of the work is to develop an intelligent system that allows both to synthesize coatings with desired properties and to investigate the properties of coatings in order to establish the influence of heterogeneous factors on them.
Materials and methods. MAO is a plasma-chemical method of hardening samples of valve metals with unipolar conductivity in the metal-oxide-electrolyte system, such as aluminum, magnesium or titanium. The coatings synthesized by this method are an oxide layer consisting of high-temperature crystalline modifications of alumina. To obtain oxide coatings, a galvanic cell is used – a bath with electrolyte in which two electrodes are immersed – an anode (a part made of a valve metal) and a cathode made of stainless steel. When developing the hardware of an intelligent system, methods of the theory of circuits, methods of measuring electrical quantities were used.
Results. The structure of an intelligent automated system that allows controlled synthesis of MAO coatings with desired properties has been developed. The hardware part of the system contains a set of measuring channels designed to monitor and measure the properties of coatings during the process. Automation is achieved through a developed intelligent application that combines content management systems and software.
Conclusions. The advantages of the proposed intelligent system are the ability to measure and control the parameters of oxide coatings in the process during the deposition of coatings; automated selection of technological regimes. This system is aimed at solving the urgent problem of fundamental science – establishing relationships between the technological parameters of the MAO process and the properties of MAO coatings, and contributes to improving the controllability of microarc oxidation technology, which contributes to the quality and competitiveness of MAO coatings produced in Russia on the world market.
