Problems solved by technology

Although it has a certain hardness, strength, corrosion resistance and scratch resistance, and at the same time, silicon dioxide is also mentioned as a transition layer, but it is mainly together with the diamond film layer, so that it can play an anti-reflection film system and The function of the high-reflection film system does not mention its requirements in terms of bonding performance; in addition, due to the influence of the light transmittance of the diamond-like carbon (DLC) layer itself, when used as a light-transmitting product, its thickness can only reach 5nm~20nm can ensure the light transmittance, and it is also because the thickness is too small, it is still easy to be worn out during use, which affects the overall wear resistance of the product

Abstract

The invention relates to a coated magnesium alloy, aluminum alloy or plastic substrate and a manufacturing method thereof, belonging to the technical field of material surface treatment. The invention aims to enhance the binding property, rub resistance and light transmittance of the substrate surface. The method comprises the following steps: carrying out alkali washing on the substrate prepared from magnesium alloy, aluminum alloy or plastic according to the required size, and drying for later use; SiO2 film coating: coating the SiO2 film on the front surface of the cleaned substrate prepared from magnesium alloy, aluminum alloy or plastic; and DLC-COX (diamond-like carbon-cyclooxygenase) layer coating: coating the nano DLC-COX film on the surface of the SiO2 film. The coated magnesium alloy, aluminum alloy or plastic substrate has higher rub resistance and light transmittance; and the technical process is simple and easy to operate.

Description

technical field [0001] The invention relates to a plated magnesium alloy, aluminum alloy or plastic substrate and a manufacturing method thereof, belonging to the technical field of material surface treatment. Background technique [0002] Most of the coating technologies in existing electronic products are applied to display panels, such as mobile phones, computers or LCD panels, which mainly consider the needs of light transmittance and hardness of the post-coating products. Coating on the surface of products such as metal or plastic is rarely considered. However, along with people's requirements for the overall aesthetics and performance of products, the performance requirements for other components other than the display screen are also continuously improved. On the other hand, due to its high hardness, wear resistance or high surface finish, its products are widely used in machinery, electronics, microelectronics and optics. Such as Chinese patent application (publica...
