American Airlines Metal (Shanghai) Co., Ltd., for everyone to explain the difference between the anode and plating of aluminum alloy such as 7075 aluminum plate:

          7075 aluminum plate is called anode treatment. Compared with the principle of electroplating, the object to be placed is placed on the anode to oxidize it to form an oxide film. This is anodization. Because of the fine structure of aluminum oxide film, it has good adsorption and is not easy to fall off. Therefore, a layer of fine oxide film is artificially applied through an anodizing device to protect it from continuous oxidation, which is useful in the anode.

         The anodizing treatment of 7075 aluminum plate is to form an oxide film by the action of electric current on the surface of aluminum metal. It is hard and wear-resistant, has high corrosion resistance and beautiful color. The aluminum alloy itself is easy to process, high in strength, widely used, and cumbersome. Tyang processing products are aluminum doors and windows, furniture, camera and instrument housing parts. Aluminum manufacturing and processing industry is also expanding, aluminum anodizing equipment processing has considerable market potential.

       The development of 7075 aluminum plate anode treatment, such as hardanodizing, is also useful for AC and DC treatment at low temperature currents. This hardened anodized aluminum can be used for pistons, cylinders, cylinder liners, hydraulic presses and turbines. Another, steam valve, gear, 'gun parts, clutch, brake disc, (brakedisk), machine see also tools, bath temperature, current density.

       Principle of Electroplating Electroplating is an electrolysis process in which a metal sheet providing a plated metal acts as an anode, an electrolyte solution is usually a metal-plated ionic solution, and a plated object acts as a cathode. After the input voltage between the anode and the cathode, the metal ions in the electrolyte are attracted to the cathode, and are plated thereon after reduction.

       At the same time, the metal of the anode is redissolved to provide more metal ions in the electrolyte. In some cases, an insoluble anode is used, and a new group of electrolytes is added to the plating to supplement the metal ions.

       The composition of the solution needs to be automatically controlled to strictly control the quality of the finished product to meet the customer's requirements. Automation requires the introduction of foreign technology and a large amount of capital, so at the same time, it is necessary to have an in-depth understanding of the potential of foreign markets to achieve automation.
