 Principles of electrochemical reactions, redox reactions in corrosiion of materials and methods for corrosion prevention and protection of materials.
 Principles and generation of energy in batteries, nuclear reactors, solar cells, wind mills and fuel cells.
 Preparation, properties and applications of engineering materials.
 Types of fuels, calorific value calculations, manufacture of solid, liquid and gaseous fuels.
UNIT I WATER TECHNOLOGY 9
Introduction to boiler feed water-requirements-formation of deposits in steam boilers and heat exchangers- disadvantages (wastage of fuels, decrease in efficiency, boiler explosion) prevention of scale formation -softening of hard water -external treatment zeolite and demineralization – internal treatment- boiler compounds (phosphate, calgon, carbonate, colloidal) – caustic embrittlement-boiler corrosion-priming and foaming- desalination of brackish water –reverse osmosis.
UNIT II ELECTROCHEMISTRY AND CORROSION 9
Electrochemical cell – redox reaction, electrode potential- origin of electrode potential- oxidation potential- reduction potential, measurement and applications – electrochemical series and its significance – Nernst equation (derivation and problems). Corrosion- causes- factors- types-chemical, electrochemical corrosion (galvanic, differential aeration), corrosion control – material selection and design aspects – electrochemical protection – sacrificial anode method and impressed current cathodic method. Paints- constituents and function. Electroplating of Copper and electroless plating of nickel.
UNIT III ENERGY SOURCES 9
Introduction- nuclear energy- nuclear fission- controlled nuclear fission- nuclear fusion- differences between nuclear fission and fusion- nuclear chain reactions- nuclear reactor power generator- classification of nuclear reactor- light water reactor- breeder reactor- solar energy conversion- solar cells- wind energy. Batteries and fuel cells:Types of batteries- alkaline battery- lead storage battery- nickel-cadmium battery- lithium battery- fuel cell H2 -O2 fuel cell- applications.
UNIT IV ENGINEERING MATERIALS 9
