Plasma-electrolytic oxidation is accompanied by microdischarges, which determine the main mechanism of coating growth. These microdischarges, along with electrolyte boiling, generate acoustic vibrations that are closely related to the coating growth process. In this paper, authors investigated the acoustic characteristics and surface properties of a zirconium alloy during plasma-electrolytic oxidation, specifically focusing on the constant voltage mode. The study identified informative ranges within the acoustic spectrum that corresponded to two distinct stages of microdischarge development. Furthermore, regression models were created to establish a strong correlation between the increase in coating thickness and changes in current density and peak amplitudes within the acoustic spectrum. The acoustic spectrum ranges of 4000-5000 Hz and 17000-18000 Hz were found to be the most informative for coating thickness diagnostic.
