| Abstract: | The applicability of a low concentration chromate passive film to hot dipped zinc aluminum alloy coated steel wires was examined. The anticorrosive ability of the passive film formed on the surface of zinc aluminum alloy coated steel wires was investigated by means of salt spray, electrochemical corrosion tests, and immersion test in artificial sea water. The composition of the film was analyzed by means of XPS and AES. The results show that the corrosion resistance of zinc aluminum alloy coated steel wires is improved remarkably with the low concentration chromate film, and the composition of the film is S 5 5,Na 3 4,C 11 8, Ti 7 9,O 41 6,Cr 13 7,Zn 16 0. |
