3 0 0 3
OBJECTIVE
The subject provides knowledge on various types of corrosion, their kinetics, testing and
methods of protection as well as introduction to tribology.
UNIT I INTRODUCTION 12
Introduction tribology, surface degradation, wear and corrosion, types of wear, adhesive,
abrasive, oxidative, corrosive, erosive and fretting wear, roles of friction and lubrication-,
expressions for corrosion rate. emf and galvanic series - merits and demerits -Pourbaix
diagram for iron, magnesium and aluminium. Forms of corrosion - Uniform, pitting,
intergranular, stress corrosion. corrosion fatigue. dezincification. erosion corrosion,
crevice corrosion - Cause and remedial measures - Pilling Bedworth ratio - High
temperature oxidation.
UNIT II KINETICS OF CORROSION 8
Exchange current density, polarization - concentration, activation and resistance, Tafel
equation; passivity, electrochemical behaviour of active/passive metals, Flade potential,
theories of passivity, Effect of oxidising agents
UNIT III CORROSION IN INDUSTRIAL PRACTICE 8
Atmospheric, pitting, dealloying, stress corrosion cracking, intergranular corrosion,
corrosion fatigue, fretting corrosion and high temperature oxidation; causes and remedial
measures, Corrosion failure – Inspection and analysis of corrosion damage
UNIT IV TESTING 8
43
Purpose of corrosion testing - Classification - Susceptibility tests for intergranular
corrosion- Stress corrosion test.salt spray test humidity and porosity tests, accelerated
weathering tests. ASTM standards for corrosion testing and tests for assessment of
wear
UNIT V PROTECTION METHODS 8
Electroless plating and Anodising - Cathodic protection, metallic, organic and inorganic
coatings, corrosion inhibitors - principles and practice - inhibitors for acidic neutral and
other media. Special surfacing processes - CVD and PVD processes, sputter coating.
Laser and ion implantation. Arc spray. plasma spray. Flame spray. HVOF.
