| Abstract: | Black chemical conversion film was pre-pared on the surface of Al alloy. The corrosion resistance of thechemical conversion film was evaluated by conducting droppingtest and immersion test and measuring polarization curve as well.The morphology and elemental composition of the chemical con-version film were analyzed by means of scanning electron micros-copy and energy dispersive X-rav analysis. Results show that thechemical conversion film on Al alloy surface looks beautifullyblack and has good corrosion re... |
