The pre-treating method what can meet the requirements, can carry out according to the property of metal works itself and state.
In some embodiments, described be oxidized to is aoxidized using sulfuric acid oxidation method.
Through peroxidation step, the oxidation film with a large amount of micropores will be formed in surface of workpiece.Metal oxide film can be with
Effective protection metallic matrix is not corroded, and the sulfuric acid oxidation method, which is aoxidized to obtain oxidation film, through the invention compares natural shape
At properties of oxide-film it is more preferable.Also there is better hardness and wearability.
Typically, there is two class of Barrier and porous type through the oxidation film that peroxidating obtains.Barrier anode oxide film is
The thin anode oxide film of one layer of dense non-porous against metal surface.Its thickness depends on additional anodic oxidation voltage, thick
Degree is no more than 0.1 μm, is mainly used for making electrolytic capacitor.Barrier oxidation film also refers to shield type oxidation film, or blocking
Layer oxidation film.Barrier layer oxidation film refers to having separation between the porous layer of Porosity anodic oxide film and metal, has barrier film character
With the oxide layer of Conduce Disciplinarian.Porosity anodic oxide film is made of two layers of oxidation film, and bottom is densification identical with barrier membrane structure
Non-porous thin oxide layer, i.e. barrier layer, thickness are related with additional oxidation voltage.Main part is honeycomb sandwich, thickness
Depending on by electricity.
It is of the invention desired by oxidation process, it can especially be obtained in surface of workpiece by sulfuric acid oxidation method more
Pass oxidation film.The oxidation film that metal is obtained through peroxidating will appear substantially undissolved situation in the electrolytic solution.For example, neutral
In borate, neutral phosphate or neutral tartrate solution, voltage rapidly rises to anodizing time when beginning
Relatively high voltage, if this voltage is increased beyond breakdown voltage, oxidation film is breakdown.If this voltage does not reach
Breakdown voltage, then under this voltage, electric current quickly fall to again close to 0 or it is a very small be referred to as leakage current value.This
The leakage current value of Shi Suoshu may be from the electronic current of the defects of film, impurity or partial thin film.This is in metal surface
The oxidation film of generation is Barrier oxidation film.
Metal surface, which is aoxidized, to be formed by oxidation film and can be partly dissolved in the electrolytic solution, and electrolyte can be grass at this time
Acid, sulfuric acid, phosphoric acid or chromic acid, voltage change is similar to the above situation when starting, but declines and not yet reach a minimum
When, relative constant steady state voltage is risen to again, maintains the electrochemical reaction of anodic oxidation, and what is generated at this time is porous
Type oxidation film.
When electrolyte is part organic acid soln, neutral sulphates salting liquid and chloride ion-containing, the speed of metal surface dissolving
The formation speed of degree and oxidation film is close, and voltage generally rises to a maximum before gradually declining.At this time in metal
Spot corrosion will occur for surface, and can not form the oxidation film of completion.
In some strong acid medias, voltage generating period fluctuation or stable on a lower voltage value, at this time
Metal surface cannot form a film, and electrobrightening only occurs.
In some strong acid or strong base solution, beginning voltage is very low and maintains low voltage level, and metal is big at this time
Electrolytic attack occurs for part surface.
In order to which Porosity anodic oxide film is made, some organic acids can also be added, to reduce electrolyte for oxidation film
Solubility property.Nonetheless, the specific choice of electrolyte, being still can not be available by limited trials.For example, sulphur
Acid is different with the solvability of oxalic acid, while addition sulfuric acid and oxalic acid, Oxidation Law also differ in the electrolytic solution, raw
At the performance of oxidation film also can different from.In factors such as micro-pore diameter, pore wall thickness and porositys, also in electrolyte
Anion, content and certain relationship is distributed with.
As anode in the electrolytic solution by electric current, negatively charged anion moves to anode surface and loses electronics puts metal
Electricity, metal lose electronics and are aoxidized as ion to make valence state increase.In aqueous solution since anion is containing aerobic, oxygen and
Metal can be in conjunction with generation oxide.The final result of this reaction is related to many factors, especially related to electrolyte, and
The factors such as property, temperature, voltage, the time of final reacting product.
