Preferred version, this solution of 1L is made up of the raw material of following quality proportioning: ferric chloride 35g, potassium ferricyanide 43g, high
Potassium manganate 0.8g, potassium peroxydisulfate 0.2g, ammonium molybdate 0.3g, distilled water adds to 1L.
Ferric chloride, potassium ferricyanide synergism, form blue material, potassium permanganate and potassium peroxydisulfate and work in coordination with as oxidant
The depth that effect regulation is blue, the mildness of ammonium molybdate regulation color.
Being divided into pre-treatment of turning blue, coloring to turn blue, turn blue the three phases such as post processing:
Pre-treatment of turning blue mainly includes electrochemical deoiling defat and alkaline etching.Electrochemical deoiling defat: aluminum alloy specimen is put into and has joined
In the oil removing degreasant solution made, carrying out oil removing defat, temperature selects room temperature, and the time is set as 10～20 minutes.Distilled water
Cleaning, the aluminum alloy surface after oil removing defat has abluent and remains in above, clean with distilled water flushing.Alkaline etching,
Aluminum alloy specimen after oil removing defat is put in 10% sodium hydroxide solution prepared, and carries out alkaline etching process, and temperature selects room
Temperature, the time is set as 10～20 minutes.The purpose of alkaline etching is to remove the natural oxide film of aluminum alloy surface, the most flat aluminium alloy table
Face, the most also can thoroughly remove the greasy dirt of aluminum alloy surface.Aluminium alloy after alkaline etching can speckle with sodium hydroxide solution, therefore uses
Distilled water is rinsed well it.
Coloring is turned blue: the oil blackeite coloring liquid prepared is put in constant-temperature heating magnetic stirring apparatus, heating in water bath to 70～80 DEG C.
The aluminum alloy specimen that pre-treatment is good is put in coloring solution, processes 5～10 minutes.
Turn blue post processing: the beaker filling distilled water is put into constant-temperature heating magnetic stirring apparatus, is heated to 90～95 DEG C,
Aluminum alloy specimen after coloring is turned blue is immediately placed in this distilled water, and sealing treatment 10-15 minute, to increase stablizing of surface
Property, take out and air-dry.
The invention have the advantages that: the surface thickness about 30～200 microns after the method process of the present invention, blueness is Teng
Blue and a small amount of Prussian blue inorganic compound forming mixing of family name, solvent resistance is good, after sealing treatment, therefore should not take off
Color.The blue surface layer generated, good decorating effect, and have good stability and certain corrosion stability, treatment temperature is low.
