Abstract
The invention discloses a local shield method of non-ferrous metal product micro-arc oxidation. The features are that making the object shielded its local according to the local surface shape without needing micro-arc oxidation; covering it by the shaped object; degreasing; cleaning; micro-arc oxidation; cleaning; taking down the object used to shield the local; processing next technology. The advantages of the invention are that it is simple and practical; it can greatly reduce energy consumption, production cost, and increase production efficiency.
Description
Technical field
The present invention relates to the non-ferrous metal field of surface treatment, the partial shield method that particularly a kind of non-ferrous metal products differential arc oxidation is handled.
Background technology
To the non-ferrous metal surface, especially the differential arc oxidation processing is carried out on the surface of magnesium and magnesium alloy, aluminium and aluminium alloy, titanium or titanium alloy, and erosion resistance, wear resistance, the insulativity of magnesium and magnesium alloy, aluminium and aluminium alloy, titanium or titanium alloy are all significantly improved.At present the non-ferrous metal products surface by micro-arc oxidation being handled all is to adopt goods are taken off ester---cleans---differential arc oxidation---dry such technical process of cleaning---sealing---; in the differential arc oxidation treating processes; its energy consumption is bigger; differential arc oxidation efficient is lower; one of them major reason is exactly; the differential arc oxidation reaction all will take place in non-ferrous metal products all surfaces that contact with electrolytic solution when carrying out the surface by micro-arc oxidation processing; and in fact most of goods need most that the differential arc oxidation layer plays a role is outside surface; the goods surface of internal cavity does not generally need the differential arc oxidation layer to protect; but when product surface being carried out the differential arc oxidation processing; the goods surface of internal cavity is forced to carry out the differential arc oxidation energy of having handled just additive decrementation; cause a large amount of energy dissipations; cause the increase of production cost, influenced applying of differential arc oxidation treatment technology.
Summary of the invention
The purpose of this invention is to provide the partial shield method that a kind of non-ferrous metal products differential arc oxidation is handled, it can be with the goods local surfaces shielding that need not handle, and the energy additive decrementation when avoiding differential arc oxidation to handle improves the differential arc oxidation processing efficiency.
The object of the present invention is achieved like this: the local surfaces shape making that needn't do the differential arc oxidation processing according to non-ferrous metal products is used for this partial object of shielding, the object that is used to shield of moulding is filled or is covered goods and needn't do the position that differential arc oxidation is handled; Then goods are taken off ester by process sequence, clean, differential arc oxidation is handled; Differential arc oxidation is handled the back cleaning article, takes off to be used for this partial object of shielding, carries out subsequent technique again.
Owing to adopted such scheme, before non-ferrous metal products being carried out the differential arc oxidation processing, the local surfaces shape making that needn't do the differential arc oxidation processing according to non-ferrous metal products is used for this partial object of shielding, goods are filled or covered to the object that is used to shield of moulding needn't do the position that differential arc oxidation is handled, when making goods in electrolytic solution, carry out the differential arc oxidation processing, owing to needn't do the position conductively-closed that differential arc oxidation is handled, electrochemical reaction can't be carried out in this part surface, the only remaining surface that need do the differential arc oxidation processing is carried out differential arc oxidation and is handled, institute's consumed power is reduced greatly, and ground plane is big more, the electric energy that consumes reduces manyly more, thereby has improved the efficient that differential arc oxidation is handled.The object that is used to shield adopts physical and mechanical properties insulating material making such as rubber, plastics, foam preferably, the object that is used in shielding can closely be filled in the goods inner chamber or cover article outer surface, can be when differential arc oxidation not be handled and goods break away from.Adopt aforesaid method that goods are carried out differential arc oxidation and handle, under the identical situation of product volume shape, can handle than the employing prior art with identical differential arc oxidation parameter and to Duo one times goods, greatly improved differential arc oxidation efficient.
The inventive method is simple and practical, and the energy consumption that differential arc oxidation is handled is reduced greatly, and the differential arc oxidation processing power is greatly improved, and can reduce production costs, and can enhance productivity again.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a kind of embodiment synoptic diagram of the present invention;
Fig. 2 is an another kind of embodiment synoptic diagram of the present invention.
Embodiment
Referring to Fig. 1, the embodiment synoptic diagram of this accompanying drawing for the goods inner chamber is shielded.At first carrying out magnesium alloy product 3 that differential arc oxidation handles as required with insulating material needn't make the surface of internal cavity shape that differential arc oxidation handles and be made into the object 2 that is used to shield this inner chamber, this object that is used to shield 2 adopts elastomeric materials to make, perhaps adopt physical and mechanical properties preferably plastics make also and can reach effect same.The object that is used to shield 1 of moulding is filled in goods 3 needn't makes the inner chamber that differential arc oxidation is handled, this object 2 and the surface of internal cavity of goods 3 are closely cooperated.Adopt the common process that the magnesium alloy product differential arc oxidation is handled then, in order goods are taken off ester, clean, differential arc oxidation is handled.When goods 3 carry out the differential arc oxidation processing in electrolytic solution 1, because object 2 shieldings that goods 3 surface of internal cavity are made with elastomeric material, electrochemical reaction can not be carried out in the surface of these conductively-closeds, the only remaining outside surface generation electrochemical reaction that need do the differential arc oxidation processing, power consumption reduces about half.Goods 3 clean after differential arc oxidation is handled, and take off then to be used for this partial object 2 of shielding, carry out subsequent technique processing again.
Referring to Fig. 2, the embodiment synoptic diagram of this accompanying drawing for article outer surface is shielded.At first carrying out Al-alloy products 3 that differential arc oxidation handles as required with insulating material needn't make the external surface shape that differential arc oxidation handles and be made into the object 2 that is used to shield this outside surface, this object that is used to shield 2 adopts plastic foam material to make, and perhaps adopts elastomeric material to make also and can reach effect same.The object that is used to shield 2 of moulding is covered goods 3 needn't make the outside surface that differential arc oxidation is handled, this object 2 is cooperated with the intimate of goods 3.Adopt the common process that the Al-alloy products differential arc oxidation is handled then, in order goods are taken off ester, clean, differential arc oxidation is handled.When goods 3 carry out the differential arc oxidation processing in electrolytic solution 1, because object 2 shieldings that goods 3 outside surfaces are made with plastic foam material, electrochemical reaction can not be carried out in the surface of these conductively-closeds, the only remaining surface of internal cavity generation electrochemical reaction that need do the differential arc oxidation processing, power consumption reduces about half.Goods 3 clean after differential arc oxidation is handled, and take off then to be used for this partial object 2 of shielding, carry out subsequent technique processing again.
