Can you please give me a quick recap of what cathodic and anodic protection is? To be cathodic protection does it have to oxidize better than the other element?
also An iron object is plated with cobalt to protect against corrosion. Does the cobalt protect iron by cathodicc protection?
My answr is no because iron oxidizez better [...]
