1. one kind by applying the anode oxidation method of the aluminum or aluminum alloy structure material that voltage carries out to the processing element in immerse to handle bathing, and described processing element is made by any aluminium that contains at least a impurity and additive and aluminium alloy structure material, and described method comprises:

  • A pair of negative plate is set, makes described negative plate in the face of described processing element;

    WithBy using electric supply installation to carry out repeatedly described processing element is applied the process of positive voltage and the process of removing electric charge, described electric supply installation comprisesThe anodizing direct supply,The discharge direct supply,Be constructed to switch that described processing element and described a pair of negative plate are connected with any one terminal of described anodizing direct supply and described discharge direct supply, described terminal have reciprocal polarity andBe connected in parallel in the electrical condenser and the regenerative loop of power supply separately with described processing element and described a pair of negative plate,Wherein, remove that employed voltage is adjusted in the process of electric charge-22V~

    -scope of 7V in.
