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

Article Preview

Abstract:

The kinetics of corrosion process on five Ni—Cr—Mo—Cu alloys designed by the empirical formula APF=4Cr/ (2Mo+Cu) in HCl solution have been investigated at the concentration range from 0.002mol/cm3 to 0.012 mol/cm3 and 20°C. It is developed that the kinetic parameters and the dependence of the corrosion resistance on the APF have discussed.
