Principles of corrosion phenomenon: Thermodynamics and kinetics: emf / galvanic series, Pourbaix diagram, exchange current density, passivity, Evans diagram.
Different forms of corrosion: atmospheric/uniform, pitting, crevice, intergranular, stress corrosion, corrosion fatigue, dealloying, high temperature oxidation- origin and mechanism with specific examples.
Corrosion testing and monitoring: Non-Electrochemical and Electrochemical methods: weight loss method, Tafel, Linear polarization and Impedance techniques.
Weldment corrosion and its control in various alloy systems: Factors governing weldments corrosion, carbon steels, alloy steels, ASS, DSS, Al alloys, case studies pertaining to power, process and petro-chemical plants.
Remedial measures to corrosion: coatings, inhibitors, cathodic protection, specific applications, economics of corrosion control and corrosion auditing.
