摘要
A colored Ti/Zr conversion coating was prepared on the surface of 6063 aluminum alloy.The conversion solution consist of hexafluorotitanic acid , hexafluorozirconic acid and organic compound.In potentiodynamic polarization test, the corrosion current density decreases to 0.134μA/cm2 from 5.366μA/cm2, which indicates an obvious improvement of corrosion resistance.
