When the oxide film is once formed, the anodic reaction and the cathodic reaction are immediately separated, and at this time, the anodic reaction is still performed at the bottom of the pores of the oxide film, i.e., the stainless steel surface, and the cathodic reaction is performed at the surface of the film. The anode reaction product M2+ diffuses outwards through the micropores, a diffusion potential difference delta psi exists between the orifice and the orifice bottom, the delta psi increases along with the increase of the film thickness, different interference colors are generated due to the difference of the film thickness, thereby completing the color deposition operation, the sword body 102 after color deposition is subjected to the film hardening treatment of the step S6, the electrolyte in the step S5 is washed, the sword body 102 in the step S5 is connected to the cathode, the cathode lead plate electrode 111 is connected to the anode, and the film hardening solution is added for hardening treatment, thereby preventing the color from falling off, the rubber bellows 104 drives the movable block 105 to move up and down in the color deposition process, so that the movable block 105 drives the rubber ring 106 and the frosted layer 107 to move up and down on the surface of the sword body 102, thereby enabling the frosted layer 107 to rub the surface of the sword body 102, and preventing the uneven color deposition caused by excessive deposition of metal ions on the surface of the sword through the frosted layer 107, and metal ions can be uniformly subjected to reduction reaction in the oxide film holes and are precipitated in the oxide film holes, so that the purpose of uniform color deposition can be achieved.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
