Patent ID: 7540950

Claim:
A process of preparing a structure by electrodeposition, the process comprising: providing an electroplating bath comprising an electrolytic solution and an anode, wherein the electrolytic solution comprises at least one base, at least one oxidizing agent comprising at least one of vanadates (VO 4 3− ), molybdates (MoO 4 2− ),tungstates (WO 4 2− ) and permanganates (MnO 4 − ), at least one silicate, and at least one zincate; introducing an electrically conductive body into the electroplating bath; and depositing a porous adhesion promoter layer on at least one surface of the electrically conductive body, the adhesion promoter layer including the same substance as the anode, and the adhesion promoter layer being deposited by cathodic reduction of metal ions of the anode and/or cathodic reduction of metal ions in electrolytic solution.
