Nikal ima visoku kemijsku stabilnost i dobru otpornost na koroziju u mnogim medijima. Its standard electrode position is -0.25V, which is positive than iron and negative than copper.Nickel exhibits good corrosion resistance in the absence of dissolved oxygen in dilute non-oxidized properties (eg, HCU, H2SO4), especially in neutral and alkaline solutions.This is because nickel has the ability to passivate, forming a dense protective film on the surface, which prevents nickel from further oxidation.
