Corrosion and Protection of Materials Used in Industrial Equipment

The resolution of the Twenty-first Congress of the Communist Party of the Soviet Union and the May Meeting of the Plenum of the Communist Patty pointed out that the development of the chemical industry. in which materials are subjected to aggressive media at high temperatures and pres- sures, requires new materials with high corrosion resistance. New structural metals, alloys, and nonmetallic materials with fairly high resistance to corrosion have been developed and put into use in recent years in the Soviet Union. However, there are problems attendant on the industrial use of these new materials which have not been solved and which require futther study in industry, institutions of higher learning. and scientif- ic research institute. This book contains investigations made by professors of physical chem- istry and corrosion of chemical equipment, their assistants, and their re- search associates. These investigations, which concern the theory of cor- rosion and practical methods of protection against corrosion, have been made in recent years. The kinetics of electrode processes occurring on an active electrode in an aggreSSive medium is considered in the atticle entitled "Corrosion of Iron in Nitric Acid Solutions Under Cathodic and Anodic Polarization." Measurements of the electrode potential and the current density were sup- plemented by measurements of the corrosion rate of the metal to elucidate these processes in greater detail.
