  • Abstract The target of this experiment is making
    the ferromagnetic ring of magnetic encorder. After dealing the
    substance, 6061 Aluminum Alloy, with oxalic acid anodic
    oxidation, phosphoric acid oxidation and Zincate Immersion
    Process seperatly, we soaked them in Dimethyformanide/water and
    used direct current ( dc )to electrodeposite Co-Cr magnetic
    film. We hope to get excellent film with mechanical and magnetic
    properties.  The result shows that the pores' density,
    diameter and alumite film's thickness of 6061 Aluminum Alloy,
    dealed with phosphoric acid anodic oxidation are better than
    those which be dealed with oxalic aid anodic oxidation. With the
    accrument of Cr's content, the film's hardness steps
    upappearantly and it's adhesion also is prefer to the one which
    be dealed withZincate Immersion Process.It's magnetic in
    perpendicular belongs to ferro-magnetic so that it can be made
    for the high denisty ring.But the electro-deposited film which
    we get from the substance of oxalic acid anodic oxidationis not
    close enough so it's magnetic becomes worse that can't not be
    made for the magnetic ring. The one which be got from the
    substance of Zincate Immersion Process can't be made for
    excellent film with mechanical propertieseither because it's
    hardness is no good enough and so is the adhesion.
