Problems solved by technology
[0003] Due to the special growth mechanism of the coating, the coating grows through the dissolution of the substrate, causing the coating to be unable to be repaired; and a large amount of heat is generated during the growth process, which causes the substrate of the part to be over-dissolved (dissolved beyond the range required by the process), resulting in the risk of scrapping the part

Abstract
The invention discloses a deep blink hole hard anodizing device and a machining method of a part. The hard anodizing device comprises a mounting-hanging frame used for vertically fixing the part and keeping a part hole opening being upwards; a cathode tube is fixed to the mounting-hanging frame, and the cathode tube and the mounting-hanging frame are insulated; a gas inlet is formed in the upper end of the cathode tube, the lower end of the cathode tube stretches into the bottom of a part hole, and a gas outlet is formed in the lower end of the cathode tube; the cathode tube and a cathode are electrically connected, and the part is used for being electrically connected with the cathode. According to the device, it is ensured that a solution, gas and heat in a deep blind hole exchange with the exterior of the hole rapidly, and therefore product quality is improved.
Description
technical field [0001] The invention relates to a hard anodizing device and processing method for deep and long blind holes of parts, belonging to the field of special process processing methods, especially suitable for hard anodizing of parts with deep and long holes (hole depth: diameter ≥ 10) and blind holes plating. Background technique [0002] In aviation products, due to the low hardness of aluminum parts (120HV-180HV), the wear resistance is poor. According to its use, the surface hardness can be increased to 350HV-500HV by hard anodizing the mating surface, and the coating It has insulation function. [0003] Due to the special growth mechanism of the coating, the coating grows through the dissolution of the substrate, causing the coating to be unable to be repaired; and a large amount of heat is generated during the growth process, which causes the substrate of the part to be over-dissolved (dissolved beyond the range required by the process), resulting in the ris...
