Studies on Oxidation behavior of Nickel based Super Alloy(Inconel 600)

The most important form of corrosion is the attack by the accelerated oxidation which takes place when the air or fuel is contaminated with certain impurities. This is a serious problem in aircraft,marine,industrial and land-base gas turbines.The formation of porus non-protective oxide scales at the surfaces and sulphides at the substrate will lead to material degradation at high temperature applications.This type of attack is generally referred by ‘hot corrosion’ which is of two types namely type-I and type-II. This paper attempts exclusively to explain the behavior of oxidation on Inconel 600, a super alloy used for high temperature applications.The kinetics of oxidation are determined and discussed.
