Problems solved by technology

[0003] However, due to the poor hardness and wear resistance of the magnesium alloy shell, the surface of the magnesium alloy shell is easy to wear and tear. At the same time, because the magnesium alloy only has a single silver appearance, it is easy to cause monotonous colors and lose its appeal to customers.

Abstract

A shell of portable electronic device consists of mg alloy base material and AI alloy film coating layer. Its preparing method includes placing mg alloy base material in vacuum film coating chamber and vacuuming said chamber, using AI metal as sputter ¿C coating target material to sputter ¿C coat a layer of AI alloy coating film on mg alloy base material surface, carrying out anode treatment on AI alloy to form a anode treated layer on AI alloy surface.

Description

【Technical field】 [0001] The invention relates to a casing of a portable electronic device and a manufacturing method thereof. 【Background technique】 [0002] Portable electronic devices, such as digital cameras, personal digital assistants (PDAs), mobile phones, etc., all have a shell to prevent electromagnetic radiation. Existing portable electronic device casings are plastic shells coated with thin metal layers (such as aluminum), such as U.S. Patent No. 6,207,089. In order to reduce electromagnetic interference around portable electronic devices and eliminate static electricity accumulation, it uses adhesives to bond superplastic alloy sheets Bonded to the inner surface of the plastic housing. However, when this method is used, the alloy flakes are easy to fall off or wrinkle because the bonding force between the alloy flakes and the plastic shell is not strong. In addition, the industry also uses alloy metals as casings for portable electronic devices (such as aluminu...
