DETERMINATION OF PROTECTIVE PROPERTIES OF ANTICORROSION COATINGS ON STEEL BY VOLTAMMETRIC METHODS
Constantly increasing requirements for protective coatings anticorrosive properties result in a need to improve the process of their formation. For this purpose, reliable easily defined criteria for the protective properties and quality of the formed anti-corrosion coatings are necessary. To date, a large number of methods have been proposed for assessing the protective properties of anticorrosion coatings on a metal surface [1, 2]. Since all corrosion processes are due to the occurrence of electrochemical reactions, electrochemical methods can be used to control the protective properties of anticorrosion coatings [3], which is characterized by high expressivity and accuracy of measurements. This work is devoted to the development of an easily defined criterion for optimal conditions for the formation of phosphate and oxide-zirconium coatings on iron using the cyclic voltammetry method.
