The Structure and Principle of the Intelligent Micro-arc Oxidation System Operation

The purpose of the work is to create an intelligent technology for obtaining oxide coatings with specified properties through an automated system being developed. The developed intelligent system implements the method of micro-arc oxidation to obtain protective oxide coatings on products made of aluminum, titanium or their alloys. The intelligent system consists of hardware, software, and information content. The software is developed in the LabVIEW graphical programming environment. The intelligent application contains three subroutines: identification of the electrophysical model parameters and optimization of process parameters to obtain the required properties of oxide coatings; visualization of the coating parameters dependences in real time on influencing factors. The algorithm of the developed automated system functioning is presented. The presence of an intelligent application allows feedback for software, in which the process current source can change the oxidation mode depending on the coating state at a given time, taking into account the required target coating parameters (thickness, porosity, hardness, etc.). The advantage of the proposed intelligent system is the possibility of implementing a regime of controlled synthesis of oxide coatings with the required properties. In turn, it makes it possible to increase the reproducibility of the MАO coatings parameters, reduce the time for testing the technological process.
