Description
Technical field
The invention belongs to the technical field of surface of automobile industry anodic oxidation workpiece, be specifically related to one and can improve aluminum
And aluminium alloy anode oxide film alkali resistance and the method for sealing of corrosion resisting property.
Background technology
Due to aluminum and the physical and chemical performance of aluminium alloy excellence itself, aluminum and aluminium alloy are at building materials, Aero-Space, automobile, mobile phone
Also become more and more extensive Deng the application in industry.Aluminium can form the natural oxide film of thin layer in atmosphere, and this layer is certainly
The oxide-film so generated does not has the performances such as the most anticorrosive, it is impossible to meet the needs of reality application.Industrial quarters is usual at present
Using alumilite process technique, aluminium, after a series of pre-treatment steps such as oil removing, polishing, alkaline etching and neutralization, is put by aluminium
It is placed in such as: sulphuric acid, in the oxidizing solution such as phosphoric acid, under the effect of electric field, makes aluminium material surface generate electrochemical oxidation film, pass through
Control electric pulse field parameter and reach to control the effect of thickness.This electrochemical conversion film generated by extra electric field mode follows crystal
The rule of growth, it has been investigated that, being generally electrochemically transformed film has two structures to constitute, at the anodised initial stage, formation
Being one layer of densification and thin " barrier layer ", during film layer slowly grows, organizational structure becomes loose, and is perpendicular to aluminum
The hole formation in material direction, people are this Rotating fields referred to as " porous layer ".The density of this micropore reached 76,000,000,000 holes/
cm2, the formation of hole changes electrochemical conversion film surface characteristic greatly, adds chemism, and this tunic can not be very
Good is applied in reality, it is thought that by the way of sealing of hole, change the microporous properties of film layer, make it to meet reality should
Demand.Carry out sealing pores and can improve the neutral salt spray ability of aluminium material surface, copper accelerated acetic acid salt spray ability, condensed water energy
Power, specking ability, acid resistance solution ability, alkali resistance solution ability, heat-resisting ability.
Traditional sealing pores is mainly the cold seal of Nickel difluoride system, boiling water is closed and the heat-sealing of nickel acetate system.And this
The drawback of several conventional hole-sealing technologies is that oxide-film is after above-mentioned sealing treatment, it is impossible to meet acidproof, alkaline-resisting, the most acidproof simultaneously
Alkaline-resisting and corrosion-resistant, high temperature resistant and resistance to sassafras such as washes at many performance requirements.Generally cold seal is remarkably improved decay resistance, but
Measuring sealing of hole quality after cold seal immediately the most defective, standing time extends, and corrosion weight loss declines on the contrary.Further, cold seal is at height
Temperature is lower is easier to occur micro-crack, and is difficult to be dried and cannot pack in time.Although cold seal corrosion resistance is preferable, but acid-fast alkali-proof performance
Difference；Individually high-temperature vapor hole sealing technology is more much higher than using heat-sealing cost；Seal, sealing of hole speed high to water quality requirement
Slowly, easily play ash, acid-fast alkali-proof better performances, but corrosion resistance is poor.
At present, market occurs in that multiple cold seal and heat-seal process agent, but due to the particularity of auto parts local environment,
Such as highly basic during carwash and friction, conventional processes all cannot meet all standard that automobile industry proposes simultaneously, it is impossible to full
The demand of foot international market.
European patent EP 1873278 proposes the sealer the using silicate aluminium anodes to having carried out sealing treatment
Oxide-film carries out post processing, and the film surface obtained has relatively same alkali resistance.Patent DE1521664 proposes alumilite process
Film first carries out sealing treatment in the alkaline aqueous solution of metalline, uses the aqueous solution of silicate to carry out post processing subsequently.Warp
The alkali resistance of the aluminium anode oxide film that above-mentioned patented technology processes is greatly improved, but the aluminum after above-mentioned processing method
Alloy cannot pass through pH1 10min+pH13.5 10min.Oxide-film continuous acid-fast alkali-proof ability, by heavy corrosion.
Chinese invention patent CN103469276A is closed by Nickel difluoride saline solution room temperature, titanium zirconium salt solution room temperature is closed,
Three step process aluminium anode oxide films of last silicate solutions high temperature closure, find aluminium anodes oxygen 20 DEG C of tests after process
Acidproof, the alkaline resistance properties of changing film are significantly improved.The present inventor reappears patent CN103469276A method and processes alumilite process
Carrying out performance test after film, repeatability is to find its continuous acid-fast alkali-proof performance (10min pH=1+10min pH=13.5) very much
Difference.
