Problems solved by technology

These metals or alloys can deposit a layer of hard film by electroplating, but metals or alloys such as aluminum alloys, magnesium aluminum alloys, and titanium alloys oxidize quickly in the electrolyte and become non-conductors, thereby preventing electroplating.

Abstract

The present invention refers to a shell, including a basal body, a chromium metal level and a chromium carbide film, wherein said basal body being metal or alloy, said chromium metal level depositing on said basal body surface, said chromium carbide film depositing on said chromium metal level surface. A shell manufacture method includes providing a metal or alloy basal body, depositing a chromium metal level on said basal body surface, depositing a chromium carbide film on said chromium metal level surface.

Description

【Technical field】 [0001] The invention relates to a housing and a manufacturing method, in particular to a metal or alloy housing and a manufacturing method. 【Background technique】 [0002] With the development of mobile communication technology, all kinds of portable electronic devices such as mobile phones, PDAs, digital cameras, notebook computers, etc. are emerging, so that consumers can fully enjoy the convenience brought by mobile technology anytime and anywhere. Electronic devices are increasingly favored by consumers. [0003] Existing portable electronic device casings generally use plastics (such as ABS plastics) as their main materials. With the development of metal forming technology, portable electronic device casings made of metal or their alloys have appeared in recent years, such as stainless steel, aluminum alloy , magnesium alloy, titanium alloy, etc. [0004] Among them, the strong surface hardness of titanium alloy material is used as the casing of port...
