; ; ; ; ;
The existence of a relative relationship between radiometrically determined corrosion rate of platinized electrodes was indicated during normal electrolysis with direct current and their polarization with alternating current in carbonate solutions. It is proposed to use the selected conditions of electrolysis with alternating current for comparative evaluation of corrosion resistance of the platinum coatings of various thicknesses and quantity. The hydrogen content of the electrodes was determined by vacuum degassing and the surface of the coating was analyzed after electrolysis with alternating current. The reasons for rapid disintegration of the platinum layer with the use of alternating current are discussed.
