Course Description

Definition and significance of corrosion. Classification of corrosion. Thermodynamic and kinetic principles of electrochemical corrosion. Passivity. Forms of corrosion:- uniform corrosion, pitting, crevice, galvanic corrosion, environmentally induced cracking, corrosion types induced by the flow velocity of the environment, effects of metallurgical structure on corrosion, corrosion related damages by hydrogen, erosion and wear. Corrosive environments: - atmosphere, soil, water and aqueous environments, concrete, high temperature environments. Principles of corrosion protection:- design, change of metal, change of environment, change of interface. Inorganic, metallic and conversion coatings. Organic coatings and inhibitors.- cathodic and anodic protection. Principles of materials selection for corrosion protection
