Method and its application.
Background technique
The features such as aluminium alloy is small, easy processing and mechanical strength are big with its specific gravity, is widely used in building for many years
In door and window, curtain wall and household electrical appliances.Traditional aluminium preparation is to form one layer of three fine and close oxygen in surface of aluminum plate by artificial technique
Change two aluminium protective films, make it have the surface visual effect of good anticorrosion ability and exquisiteness, to be applied to very much
High-end decoration or manufacturing field.
Traditional anode oxidation process is placed in electrolyte solution and is powered using aluminum or aluminum alloy product as anode
Processing makes the process of its surface formation aluminum oxide film, the referred to as anodized of aluminium and aluminium alloy using electrolysis.Through
Anodized is crossed, aluminium surface can generate the oxidation film of several microns to several hundred a microns.Compared with the Native Oxide of aluminium alloy
Film, corrosion resistance, wearability and dicoration all improve significantly and improve.Anode oxide film hardness with higher and wear-resisting
Property, extremely strong adhesive ability, stronger adsorption capacity, good corrosion stability and electrical insulating property and high thermal insulation.Due to this
A little special performances, are allowed to all have been widely used in all respects.The main application of anodic oxidation has: (1) improving part
Wear-resisting, corrosion resistance, weatherability corrosion；(2) hyaline membrane that oxidation generates, can colour and various colour films are made；(3) as electricity
Vessel media film；(4) binding force with organic coating is improved, coating bottom is made；(5) it is electroplated, the bottom of enamel；(6)
Other purposes of exploitation, solar absorption panels, dry lubrication film, catalyst film, nano wire, deposit in perforated membrane superelevation hard films
Magnetic alloy makees memory cell.
