Abstract: Disclosed is a solution composition which may be used for a single-bath electrochemical passivation and a method using the same. The solution composition includes a metal cation, a metal-oxide anion; and an organic ligand, and optionally includes a non-metallic oxide anion or a polymer. The solution composition may prevent undesired precipitation of metal oxides before performing passivation. In addition, the method of passivation using the solution composition in a single-bath use is also provided.
