In the field of anodic oxidation, it provides services for mainstream main engine factories in the industry, such as APPLE, DELL, HP, HUAWEI, ASUS, SONY, LENOVO, etc., grasps the operation process and process specifications of mainstream manufacturers, pays close attention to the new technology and development trend of anodic oxidation industry, and studies and updates anodic oxidation equipment to meet the needs of emerging processes.
Electroplating is an electrochemical process and also an oxidation-reduction process The basic process of electroplating is to immerse the parts in a solution of metal salts as the cathode and a metal plate as the anode. After connecting to a DC power supply, the required coating is deposited on the parts
Not all metal ions can be deposited from aqueous solutions. If the side reaction of hydrogen ion reduction to hydrogen dominates on the cathode, it is difficult for metal ions to precipitate on the cathode According to experiments, the possibility of metal ions electrodepositing from aqueous solutions can be obtained from the periodic table of elements, and anodes are divided into soluble anodes and insoluble anodes. Most anodes are soluble anodes corresponding to the coating, such as zinc anodes for zinc plating, silver anodes for silver plating, and tin lead alloy anodes for tin lead alloy However, a few electroplating processes use insoluble anodes due to the difficulty of anode dissolution, such as acidic gold plating, which mostly uses platinum or titanium anodes The main salt ions in the plating solution are supplemented by adding a prepared standard gold containing solution Chromium plated anodes use insoluble anodes such as pure lead, lead tin alloys, and lead antimony alloys.
