For the electrochemical polishing method to metal products 2 of the present invention specifically describes, referring to accompanying drawing 1-3.Based on these accompanying drawings, the embodiment of the device 4 that is used to polish metal products 2 of the present invention has been described also.
Therefore, Fig. 1 has provided the storage tank 5 that comprises electrolyte solution 1 of the present invention, wherein storage tank 5 be divided into two in the bottom interconnective groove or container 7 and 8 and separately by vertical dividing wall 6.First container 7 is designed to contain the anode of the electrochemical reaction that the above-mentioned metalwork 2 by polishing forms.Described metalwork or goods 2 are fixing by guaranteeing to have with it the tightening device that electrically contacts and be arranged in first container 7 or metal frame (as hook), and described tightening device or metal frame also contact (though not illustrating) with the positive pole terminal (positive pole) of current source.
In addition, the separating tool 9 that comprises liquid permeable solution in the bottom of first container 7 of storage tank 5, therefore second container 8 that contains electrolyte solution 1 limited by vertical partition 6 and cooperate with it, and wherein said electrolyte solution 1 links to each other with first container 7 via described permeable separating tool 9.These separating tools 9 are made up of the band with a plurality of holes.The preferable separation instrument is made up of mesh screen or net.
Second container of storage tank 5 or groove 8 comprise the instrument 10 that makes liquid or electrolyte solution 1 concussion.At this moment, shown in Fig. 1-3, described concussion instrument 10 is made of the vertical piston that slides in described second container 8, makes that the level in electrolyte solution 1 first container 7 in the storage tank 5 increases during by permeable separating tool 9 to some extent at described solution 1.
Along with electrolyte solution 1 leads to another container by a container, can in first container 7, form the fluidized-bed of unreactiveness particle 3, by among Fig. 2 and Fig. 3 as can be seen its in suspension.
Fig. 2 represents piston 10 with vertical arrows and the working direction of the metalwork 2 that will polish, and the direction of horizontal arrow points electrolyte solution 1 when piston 10 descends in second container 8.
Identical arrow scheme is used among Fig. 3, and wherein the working direction of piston 10 is opposite, and it moves now backward, and the working direction of the metalwork 2 that anode maybe will polish is also for making progress.The change of the travel direction of piston 10 has realized getting back in second container 8 of part electrolyte solution 1.This compacting unreactiveness particle 3.In this way, around metalwork 2, reach maximum particle 3 density, and reach the maximum friction with the metallic surface 13 that will polish thus.
Use can allow multiple change and need not to depart from purpose of the present invention for this reason such as the described device 4 that is used for polishing of metal articles 2, can use finishing method by between negative electrode and anode, applying electric current, it comprises that at least one makes described anode and size greater than 3 contacted stages of unreactiveness particle of 100 microns, the metalwork 2 of wherein said anode for polishing.
Can also comprise following circulation by the method for Fig. 1-3 set: one of them semi-period is that anode interacts or submergence (referring to Fig. 1) with the electrolyte solution 1 that does not contain inert particle 3; And semi-period is the metal products 2 that will polish or anode contact with the electrolyte solution 1 that contains inert particle 3 in suspension (referring to Fig. 2 and Fig. 3).
Anode can be divided into two stages or step with the 1 contacted semi-period of electrolyte solution that is suspended with unreactiveness particle 3 therein: in first stage, particle carries out fluidisation and anode submergence in fluidized-bed 14; Second stage, make unreactiveness particle 3 compactings around the metal products that will polish to contact in mode (as shown in Figure 3) the most closely with it.
At last, though do not illustrate, but after making the metalwork or unreactiveness particle 3 compactings around the goods 2 that will polish, wherein make described goods 2 and the 1 contacted semi-period of electrolyte solution that does not contain unreactiveness particle 3, this is similar to the situation of Fig. 1.
Can polish the comparatively complicated and goods 2 that when handling, have problem of geometry such as the combination of described electrolyte solution 1 and this finishing method of application with mechanical means or method; We can emphasize excessive change circle, the level and smooth deficiency in depression 15, over-drastic processing or polishing time, modification, the formation depression in outstanding corner etc. in these problems.
Yet, use electrolyte solution 1 of the present invention and method, can realize perfectly polishing and do not have rough and uneven in surface or be at most tens microns roughness 11, this is because there is the compound of the alkyl benzene sulphonate (ABS) family of at least a formula I, and more preferably there are the dialkyl benzene sulfonic acids compound of at least a 10-14 of having carbon atom alkyl and the benzene sulfonamide acid compound of at least a 10-14 of having carbon atom alkyl, can around the metal products 2 that will polish, form anode layer 12 with supramolecular structure.
Can see among Fig. 4 that the anode that constitutes electrochemical reaction has the metal products 2 of projection or coarse 11, film that it is illustrated by the broken lines or anode layer 12 center on, and it is along the profile of metal 2 and represent the oversubscription sub level of described electrolyte solution 1.Give and metal 2 interactional unreactiveness particles 3.
Described anode layer 12 with supramolecular structure can have tens micron-sized fixed thickness.In addition, it has resistance and the better mechanoreception (mechanical susceptibility) bigger than the rest part of ionogen 1, thereby the goods that will polish therein 2 with contain the electrolyte solution of suspension unreactiveness particle 3 in 1 contacted semi-period, the latter is tending towards passing through mechanical erosion, preferably the convex part 11 that will polish by mechanical erosion is removed anode layer 12, is easy to effectively replace the anode layer that is present on described projection or coarse 11 to adjacent space that is lower than them or hole 15.
The preparation of electrolyte solution 1 of the present invention is easy to form the anode layer with the physics-electrical properties gradient that does not have the continuity restriction on perpendicular to the thickness of anode layer 12.When producing such thickness and rough and uneven in surface degree 11 anode layer 12, realized degree extremely different rough and uneven in surface degree or roughness 11 are effectively evened up in same levels.
Therefore, as using Fig. 4 that arrow shows as can be seen, when the anode layer 12 of unreactiveness particle 3 and supramolecular structure interacts, move to adjacent recessed surface or recessed face 15 near the material or the solution 1 of the raised points 11 of metal products 2.Along with the carrying out of finishing method, obstruction inert particle 3 gets more and more with the phenomenon that metal covering 13 directly contacts and occupies advantage.In other words, because do not have turbulent flow as limit layer near the adhesion coating of anodic on statistics, it does not almost upgrade.
