Description

Ionic liquid aluminizing electroplating equipment under inert atmosphere Technical Field The invention belongs to the technical field of electroplating equipment, and particularly relates to ionic liquid aluminum plating electroplating equipment under an inert atmosphere. Background The ionic liquid plating is used as an innovative electroplating technology, adopts the ionic liquid of a nonaqueous system as electrolyte, has unique advantages, can realize the electroplating processing of active metals such as aluminum, and the like, cannot be electrodeposited from aqueous solution, thoroughly avoids the risk of hydrogen embrittlement, is particularly suitable for the surface treatment of easily oxidized metals, is environment-friendly and free from pollutant emission in the whole electroplating process, and has wide application prospects in the surface aluminum plating fields of 3C product accessories, power semiconductor wafers, die-casting aluminum alloys, neodymium-iron-boron and other workpieces. However, ionic liquids have extremely strong hygroscopicity, and can rapidly absorb moisture when being exposed to air, so that the physicochemical properties of the electrolyte are irreversibly changed to fail, and the electrochemical performance of the electrolyte is seriously affected. The electrodeposition process of aluminum has extremely severe requirements on environmental purity, and the existence of trace water and oxygen can greatly compress an electrochemical window of the ionic liquid electrolyte to cause side reactions on the surface of an electrode, so that the defects of oxidation of a coating, poor uniformity of a coating and the like are caused, and finally, the quality of a product is seriously reduced. Therefore, the industrial application of the ionic liquid aluminizing technology is highly dependent on a dedicated sealing device capable of providing a stable anhydrous oxygen-free inert atmosphere. The vacuum glove box commonly adopted in the current industry exposes a plurality of technical defects in practical application, and is difficult to meet the technological requirements of the ionic liquid aluminizing. The equipment can only provide basic inert gas protection and drying environment, is not customized according to the whole process characteristics of the ion liquid aluminizing, cannot integrally complete activation cleaning before aluminizing, aluminizing process and cleaning process after aluminizing in the same equipment, and needs to be additionally provided with other equipment for auxiliary operation, so that the technological process is broken and the production efficiency is obviously reduced. The purifying system has limited capability, is difficult to control the water oxygen content in the box body to be in an ultralow level, can not reach the strict standard required by the aluminizing of the ionic liquid, and influences the long-term stability of the electrolyte. The equipment lacks an effective low-temperature regulation and maintenance mechanism, and for ionic liquids which are very easy to absorb moisture or electrolyte additives which need to be stored at low temperature and electroplating semi-finished products, operators have to frequently take materials out of a box body and put the materials into an external refrigerator, and moisture and oxygen are very easy to bring in during the process of transportation, so that material pollution and product quality fluctuation are caused. The transition bin has unreasonable structural design, and the material has insufficient tightness when being transported inside and outside the box body, so that atmosphere leakage is easy to occur, and the integrity of an internal inert environment is damaged. The observation window glass and the metal parts of the equipment do not adopt targeted anti-corrosion measures, and after the observation window glass and the metal parts are contacted with acidic substances generated by volatilization or reaction of the ionic liquid electrolyte for a long time, corrosion damage easily occurs, so that maintenance cost is increased, atmosphere sealing failure can be caused, and the stability of an aluminizing process is further influenced.
