DOIAbstract
The paper discusses the effect of the electrolyte composition on the protective properties of the PEO coating on the Zr-1Nb zirconium alloy. To assess the functional properties of the coatings, its topography and microstructure, elemental and phase content were studied, and electrochemical and accelerated operational tests to identify the most efficient electrolyte were performed. It was found that the coatings obtained in the silicate-phosphate electrolyte exhibit the best protective properties
