Description

The surface treatment method of metal works
Technical field
The invention relates to a kind of surface treatment method of metal works, especially about the dyeing process on the metal works surface after a kind of anodic oxidation treatment.
Background technology
As everyone knows, alloy materials such as aluminium, titanium, magnesium have advantages such as intensity height, light weight, and it is widely used in fields such as aviation, electronics, communication.But, the easy to wear and corrosion of alloy materials such as magnesium, aluminium, titanium, in order to improve alloy material surface quality such as magnesium, aluminium, titanium, industry adopts anodic oxidation treatment technology to reach usually.
Metal works surface after the anodic oxidation treatment can form the metal oxide film with vesicular structure.Described oxide film has the good adsorption effect to the colored component of dyestuff.Therefore, with described oxide film be substrate further to the processing of dyeing of described metal works, then can make described metal works have advantages of good abrasion, corrosion resistance nature, can make described metal works surface have bright colour again simultaneously.
Yet for the metal works of laser welding, there is small slit in its weld, and in anodised process, anodizing solution may penetrate into the depths in described slit.And the anodizing solution of depths, described slit be difficult to is removed in follow-up washing, makes the easy residual acid anodizing solution of metal works weld.Therefore, when dyeing was handled, the metal works weld can will not dye because of residual acid anodizing solution or fade.
Summary of the invention
In view of above-mentioned condition, be necessary to provide a kind of stain-fast surface treatment method of weld that improves metal works.
A kind of surface treatment method of metal works may further comprise the steps: a metal works is provided, and it has a welding zone that forms in welding; Anodic oxidation treatment is carried out on described metal works surface, to form an anode oxide film on described metal works surface; Described metal works is placed an activation solution, described welding zone is carried out activation treatment; Wash described metal works surface; Described metal works be impregnated in the processing of dyeing in the staining fluid; Wash described metal works surface; Described metal works surface impregnation in a pore-sealing liquid, is carried out sealing of hole and handles.
Compare prior art, the surface treatment method of metal works of the present invention carries out activation treatment in the welding zone on described metal works surface, help avoiding the welding zone in the anodic oxidation processing procedure, to permeate oxidation treatment liquid in its weld seam, thereby prevented that the welding zone from will not dye or fade in the dyeing processing procedure painted influence.
Embodiment
The surface treatment method of metal works of the present invention is applicable to the process of surface treatment of aluminium, titanium, magnesium metal or its alloy product.
The surface treatment method of the described metal works of better embodiment of the present invention may further comprise the steps:
One metal works is provided, and it can be metal or its alloy products such as magnesium, aluminium, titanium.This metal works is formed with a welding zone in laser welding.
Clean this metal works with sodium hydroxide solution or sodium carbonate solution, this metal works is carried out skimming treatment with this.
After this metal works carries out skimming treatment, it is inserted in the washing bath clean, remove its surperficial impurity.
Chemical rightenning is carried out on this metal works surface handled, remove the macroscopic irregularity on this metal works surface, and obtain level and smooth metallic surface.
Wash this metal works, remove residual chemical brightening solution.
Metallic surface after chemical rightenning is handled has the layer of metal oxide compound and produces, i.e. alleged black film usually therefore need be after chemical rightenning is handled carries out workpiece pickling removing black film, and obtains light, purified metallic surface.The described pickle solution that removes black film can be chromic acid lotion.
An anodic oxidation treatment step is implemented on this metal works surface, so that this this metal works surface forms an anode oxidation membrane.The embodiment of this anodic oxidation treatment step is described as follows: use basic solution, as sodium hydroxide solution (NaOH), sodium carbonate solution (Na 2CO 3) clean this metal works; Place the anodic oxidation treatment groove to carry out anodic oxidation treatment this metal works, form anode oxide film on the metal works surface.Wherein, the anodic oxidation treatment solution concentration that is weight percentage is 0.2～1.0% phosphoric acid (H 3PO 4), processes voltage is 20～60V, current density is at 10～50mA/cm 2Between, at room temperature handled about 20 minutes.Understandable, the anodic oxidation treatment solution of this anodic oxidation treatment step also can be sulphuric acid soln, and described sulphuric acid soln concentration can be 100～200g/l, and processes voltage is 8～16V, and current density is 10～20mA/cm 2
Wash this metal works, remove the anode oxidation treatment liquid of metal works remained on surface.
Metal works after the anodic oxidation treatment is placed an activation solution, at room temperature make the welding zone activation of metal works.Described activation solution is a salpeter solution, and the weight percent concentration of described salpeter solution is 10%～30%.Wherein, described salpeter solution can effectively be replaced in the anodic oxidation processing procedure and be permeated in the anode oxidation treatment liquid of the weld seam of described welding zone, and is easy to remove in follow-up manufacturing process for cleaning.
Wash this metal works, remove the activation solution on metal works surface.
Metal works after the anodic oxidation treatment is dipped in fills in the staining trough of organic dye solution that concentration is 1～10g/l, described metal works was handled in staining trough 5～10 minutes.In this step, the chromatoplast of described organic dye adsorbs by physics or chemical action or is filled in the vesicular structure of anode oxide film.
Wash this metal works, remove the dyestuff of metal works remained on surface.
Placing hole sealing solution antianode oxide film to carry out sealing of hole this metal works handled 10～60 minutes.Wherein, hole sealing agent can be nickel salt, and as nickel acetate or nickelous fluoride, the temperature of hole sealing solution is 90～96 ℃.
Metal works washing back oven dry after sealing of hole is handled then can obtain to have good colour, has the decorative metals workpiece of advantages of good abrasion, corrosion resistance nature simultaneously.
