Study On Titanium Negative Pole Plate Of Micro-arc Oxidation And Silk-screen Printing

The nickel buckle is the nickel high added value extends the product, the technology content is high, is widely utilized in the defense-related science and technology, the fine refinement galvanization profession, has the broad market prospect.At present uses in the electrolysis production nickel buckling the pole plate the method mainly to divide the permanent pole plate and the non-permanent pole plate two big kinds.Use silk screen prepares the non-permanent pole plate produces nickel buckle, regardless of is the chemical composition, the single weight, the density, includes physical outward appearance qualities and so on the blowhole, bunching all has achieved the international advanced level.But used the silk screen to leak a pole plate leakage quantity which the print resulted in still not to be under the basic control, the analysis thought this formed the blowhole with the printing ink level gas escape to concern.How but prevented the gas escape creates the blowhole, the practice proved only is carries on the control through the change drying craft, cannot eliminate completely. On the other hand, the silk screen pole plate produces after the electrolysis a cycle takes a kickback, in the original nickel buckles the growth peripheral by the nickel to buckle the cover the printing ink level to appear becomes less crowded the flaking phenomenon, the analysis thought is the printing ink component and the pole plate crossing linking density concerns lowly.In order to solve the silk-screen printing pole plate craft above two problems, union micro arc oxidation technology characteristic:Namely has the metallurgy in the substrate home position growth to tie gathers the ceramic membrane; And the ceramic membrane compact even, has the good thermal stability, the corrosion resistivity and the insulating ability.The consideration first carries on the micro arc oxidation in the titanium pole plate surface, causes an its surface production ceramics membrane, and using this oxide film surface special hole appearance, carries on the silk-screen printing again, most must arrive has the ceramic first floor, the printing ink compound level titanium pole plate.This article first conducts the research to the titanium pole plate micro arc oxidation craft.Through the ceramic film which to under the different principal components density, the different oxidized time, the different oxidized voltage the system results in carries on thickness, degree of hardness, the superficial appearance, composes and so on the performance research, had found the appropriate micro arc oxidation craft. The union had the silk-screen printing printing ink craft, the manufacture has the ceramic first floor printing ink compound level pole plate.And after only carries on the micro arc oxidation the titanium pole plate, only carries on printing ink printing the titanium pole plate, the compound titanium pole plate as well as the electrolysis production compound titanium pole plate superficial appearance and the film binding force conducts the research.Discovered the micro arc oxide layer may enhance the printing ink level greatly the adhesion.
