Question:
Given active-passive alloys A and B having the following electro-chemical parameters:
Ecorr,V Icorr,A Βcorr,V Epp,V Ipass,A Etr,A
Alloy A -0.400 1×10-6 +0.1 0 1×10-5 +0.7
Alloy B -0.200 1×10-7 +0.1 +0.3 1×10-6 +1.2
a. Which will be the more corrosion resistant in reducing conditions (active state) Why?
b. Which will be the more corrosion resistant in the passive state? Why?
c. Which is more easily passivated by dissolved oxidizers? Why?
d. Which is more corrosion resistant in strongly oxidizing solutions? Why?
e. Which would be the more easily protected by anodic protection? Why?
