Abstract

Structural features of a set of equipment for corrosion-mechanical and electrochemical studies of materials in a high-temperature aqueous medium are described. The autoclave equipment, in contrast to the known one, allows one to clear the working electrode in the medium at high temperature under pressure and to investigate the electrochemical processes on the freshened surface. Special attention is paid to the features of the methodical approach to the choice of the type of a design and to the implementation of electrochemical experiments.
