Room temperature, the time is set as 10～20 minutes.The purpose of alkaline etching be remove aluminum alloy surface natural oxide film, just flat aluminium alloy table
Face, while can also thoroughly remove the greasy dirt of aluminum alloy surface.Aluminium alloy after alkaline etching can speckle with sodium hydroxide solution, therefore with steaming
Distilled water rinses it well.
Coloring is turned blue：The oil blackeite coloring liquid for having prepared is put in constant-temperature heating magnetic stirring apparatus, heating in water bath to 70～
80℃.The good aluminum alloy specimen of pre-treatment is put in coloring solution, is processed 5～10 minutes.
Turn blue post processing：The beaker for filling distilled water is put in constant-temperature heating magnetic stirring apparatus, 90～95 DEG C are heated to,
Aluminum alloy specimen after coloring is turned blue is immediately placed in this distilled water, sealing treatment 10-15 minutes, to increase stablizing for surface
Property, take out and air-dry.
The invention has the advantages that：About 30～200 microns of surface thickness after method of the present invention process, blueness is
The blue and a small amount of Prussian blue inorganic compound for forming mixing of Teng Shi, solvent resistance is good, Jing after sealing treatment, therefore should not take off
Color.The blue surface layer of generation, good decorating effect, and have good stability and certain corrosion stability, treatment temperature is low.
