Method for measuring the micro-discharges temperature in the micro-arc oxidation process

Abstract

Abstract An automated method for measuring the micro-discharges temperature in the micro-arc oxidation process, allowing measurements to be carried out in real time, is proposed. The design of the measuring transducer, as well as a structural metrological model, taking into account measurement errors is proposed. The possibility of establishing the dependences of the oxide layer micro-hardness on the influencing factors of the micro-arc oxidation process using the Kolmogorov-Johnson-Mehl-Avrami equation by measuring the micro-discharges temperature is shown.
