The micro arc oxidation process is to change the working area into a high-voltage discharge area. Through the specially configured liquid, a layer of film with high toughness and close connection with the substrate is formed on the surface of the product. This film has good wear resistance, high temperature resistance, corrosion resistance and electrical insulation. This process reduces pollution and is simpler to operate. It is a process in line with the "green environmental protection and sustainable development strategy". It can be applied to surface treatment of materials in various fields. Today we mainly talk about the application of micro arc oxidation process to notebook computers.

Laptops are essential for us today, and they are indispensable for both work and study. Therefore, the performance of notebook computers is the focus of users and the direction of computer manufacturers. At present, the new process adopted by notebook computer manufacturers Lenovo, Dell, Microsoft, etc. is micro arc oxidation process, which can greatly improve the wear resistance, toughness and impact resistance of notebook computer shells. PPS material is recognized as one of the six major engineering plastics, with excellent comprehensive performance and high cost performance. It is widely used in automobile manufacturing, electronic appliances, aerospace and other fields. Using PPS material to make computer antenna slot will have better performance than pure metal material.

At present, the computer shells on the market are made of metal materials after micro arc oxidation. Although it does not affect the use, the signal may be poor, because the metal materials have the characteristics of shielding the signal. But using PPS materials to make the antenna slot of the laptop shell does not need to worry about this. The reason why PPS materials are not widely used as notebook enclosures is that the voltage applied by PPS materials cannot exceed 300V during micro arc oxidation, which greatly limits the application of PPS materials.
