CONTENTS OF MODULE 2
MODULE-II: Corrosion and Metal Finishing Corrosion:
~Corrosion:
Introduction, Electrochemical theory of corrosion, Factors affecting the rate of corrosion: ratio of anodic to cathodic areas, nature of corrosion product, nature of medium – pH, conductivity and temperature. Types of corrosion - Differential metal and differential aeration - pitting and water line).
