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

摘要

The kinetics of corrosion process on Ni-Cr-Mo-Cu alloys designed by formula APF=4Cr/(2Mo+Cu) in H_2SO_4 solution have been investigated from the concentration of 0.002mol/cm~3 to 0.012mol/cm~3 at 20°C. 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 H_2SO_4 solution depend on the APF in regular way.
