Electrochemical Noise Analysis of Nickel Based Superalloys in Acid Solutions
In this paper we study the corrosion behavior of nickel-based superalloys (Inconel 690, Inconel 718, Incoloy 800, Incoloy 825), compared with commercial steels (carbon Steel 1018 and stainless steel 304), in acid (10% H2SO4 and 10 % CH3COOH) and H2O at room temperature, by electrochemical noise tech...

| description | In this paper we study the corrosion behavior of nickel-based superalloys (Inconel 690, Inconel 718, Incoloy 800, Incoloy 825), compared with commercial steels (carbon Steel 1018 and stainless steel 304), in acid (10% H2SO4 and 10 % CH3COOH) and H2O at room temperature, by electrochemical noise technique, with sampling 1024 points per second. Statistical analysis of electrochemical noise technique yielded LI localization index, the type of corrosion and the noise resistance as well as the corrosion rate. The corrosion rates of 304 stainless steel and carbon steel where much higher than nickel base alloys. Current noise time series indicate superalloy have mostly noble potentials, but depends on the electrolyte. Nickel base superalloys have good response to low temperature corrosion, but tend to localized corrosion in the electrolyte tested. |
