Methodology for Choosing a Method and Instruments of Measuring Technological Modes and Parameters of Synthesized Coatings According to Technical and Economic Indicators

It has been shown that in order to obtain oxide coatings with desired properties, in the process of their synthesis, it is necessary to measure and control the technological parameters and properties of the coatings. The authors proposed an automated system for the synthesis and study of coating parameters by the micro-arc oxidation method. An algorithm for the selection of methods and instruments for measuring technological modes and parameters of synthesized coatings according to technical and economic indicators and a method for choosing the optimal means for measuring technological parameters of the microarc oxidation process according to technical and economic indicators based on the average gain criterion have been developed. The analyzed technical indicators include metrological characteristics of measuring instruments. The technique was implemented in the selection of optimal measuring instruments for coating parameters in the process of micro-arc oxidation, which confirmed the relevance of the development of an automated system for the synthesis of coatings with specified properties, with a relative measurement error of the parameters not exceeding ±0.5 % by micro-arc oxidation.
