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

摘要

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/cm~3 to 0.012 mol/cm~3 and 20 °C. It is developed that the kinetic parameters and the dependence of the corrosion resistance on the APF have discussed.
