CHEMISTRY

Unit 1

Basic principles: Free energy concept of corrosion – different forms of corrosion – Thermodynamic & Kinetic aspects of corrosion: The free energy criterion of corrosion possibility – Mechanism of Electrochemical corrosion – Galvanic and Electrochemical series and their significance.

Corrosion Control: Materials selection – metals and alloys – metal purification – non metallic – changing medium.

Unit 2

Anodic and cathodic protection methods – Coatings – metallic and other inorganic coatings – organic coatings – stray current corrosion – cost of corrosion control methods.

Corrosion protection by surface treatment: CVD and PVD processes – Arc spray – Plasma spray – Flame spray. Corrosion

Inhibitors: Passivators – Vapour phase inhibitor.

Unit 3

Stress and fatigue corrosion at the design and in service condition – control of bacterial corrosion. Corrosion protection: Automobile bodies – engines – building construction.
