The passivation of iron in ammoniacal solutions containing copper (II) ions [PDF]

open access: yes, 2012
In the present study it was found that the presence of millimolar amounts of copper (II) ions in ammoniacal solutions leads to the spontaneous formation of a stable passive layer on metallic iron and iron alloys with nickel and cobalt, under conditions ...
