MY1354 CORROSION ENGINEERING
1. CORROSION PRINCIPLES
Electrochemical and thermodynamic principles, electrode potential of metals, EMF and galvanic series, merits and demerits, Pourbaix diagram and its importance to iron, aluminium and magnesium metals, corrosion rate expressions. Exchange current density, polarization - concentration, activation and resistance, Tafel equation, passivity, electrochemical behaviour of active-passive metals, factors governing metals exhibiting passivity, mixed potential theory and its application.
2. FORMS OF CORROSION
Atmospheric, galvanic, crevice, pitting, stress corrosion cracking, intergranular corrosion, corrosion fatigue, hydrogen damage, cavitation, fretting corrosion and high temperature oxidation-description, causes and remedial measures.
3. CORROSION TESTING
Purpose of testing, laboratory, semi-plant and field tests, susceptibility tests of IGC, stress corrosion cracking and pitting, sequential procedure for laboratory and on site corrosion investigations, ASTM standards for corrosion testing; polarization methods to measure corrosion rate.
4. CORROSION PREVENTION
Corrosion prevention by design improvements, anodic and cathodic protection, metallic, non-metallic and inorganic coatings, mechanical and chemical methods and various corrosion inhibitors
5. CORROSION IN INDUSTRIES
Corrosion in fossil fuel power plants, automotive industry, chemical processing industries, corrosion in petroleum production operations and refining, corrosion of pipelines.
