Year : 2023 | Volume :11 | Special Issue : 08 | Page : 63-73



Low alloy CrMoV steel is used in Turbine wheels, Distance pieces, Compressor aft shafts etc of Gas Turbines. Cryogenic heat treatment was used to examine the effects on the corrosion resistance of low alloy CrMoV steel. In order to eliminate residual stresses and boost wear resistance in steels and other metal alloys, cryogenic heat treatment (CHT) employs cryogenic temperatures (i.e., below – 190°C) to treat work parts. Cryogenic treatment is desired not only for the benefits it provides in the areas of stress relief and stability or wear resistance, but also because of the improvement it provides in corrosion resistance. The nuclear, pharmaceutical, and food processing sectors all have a vested interest in accurately measuring very low corrosion rates, where minute amounts of contamination and impurities are a problem. In the current investigation electrochemical methods (Tafel Analysis, NOVA software) are used to characterize corrosion mechanisms and predict corrosion rates. To understand the effect of Corrosion rate and Polarization resistance was performed in 3.5% Nacl. The Corrosion resistance of cryogenically treated sample was found to be much better than the un-treated sample and Hardness of the cryo-treated sample is also improved after Cryogenic heat therapy.

Keywords: Cryogenic Treatment, Tafel Analysis, Corrosion rate, Polarization Resistance, NOVA software
