The Dependence of the Corrosion Resistance of Ni-Cr-Mo-Cu Alloy to H2SO4 Solution on the 4Cr/ (2Mo+Cu)

Abstract:

The kinetics of corrosion process on Ni-Cr-Mo-Cu alloys designed by formula APF=4Cr/(2Mo+Cu) in H₂SO₄ solution have been investigated from the concentration of 0.002mol/cm³ to 0.012mol/cm³ at 20 . Analytical expressions for cathodic reaction were developed for the reduction of H+ and the reduction of oxygen. It is discussed that the corrosion resistance to H2SO4 solution depend on the APF in regular way.
