Problems solved by technology

[0003] There are two main types of portable electronic device casings at present. One is the metal casing, which has a relatively single color. Even if protective or decorative coatings such as baking varnish and electroplating are formed on the surface, it is often caused by improper collision during use. The phenomenon of skin peeling makes the appearance no longer beautiful and eye-catching; the other type is plastic shell, although there are many colors, but because the material is not hard enough, it is easy to scratch the surface of the shell during use and damage the original beautiful

Embodiment Construction

[0018] see figure 1 , the electronic device housing 10 according to the first embodiment of the present invention includes a metal base 12 and a ceramic coating 14 .

[0019] The metal base 12 can be made of stainless steel, aluminum alloy, etc., and its thickness is about 0.4-0.6 mm, and in this embodiment it is 0.5 mm. The metal base 12 includes a first surface 122 and a second surface 124 opposite to the first surface 122 . The first surface 122 is a rough surface with a roughness Ra of about 1.3-2.0 μm. The ceramic coating 14 is directly formed on the first surface 122 and covers the entire first surface 122 . The ceramic coating 14 is made of aluminum oxide (Al 2 o 3 ), ferric oxide (Fe 3 o 4 ), titanium oxide (TiO 2 ) and other oxide ceramic materials, its thickness is about 0.12~0.14mm, and its surface roughness is 0.1~0.3μm. Because the above-mentioned ceramic materials have their own color, the ceramic materials can be selected according to the needs of the co...

Abstract

The invention provides a housing of an electronic device, which comprises a metal matrix and a ceramic coating, wherein the thickness of the metal matrix is 0.4-0.6mm, the ceramic coating is directly formed on the surface of the metal matrix by hot spraying, and the surface of the metal matrix, which is in contact with the ceramic coating, is the rough surface after roughening treatment. The invention further provides a manufacturing method of the housing of the electronic device.

Description

technical field [0001] The invention relates to an electronic device casing, in particular to an electronic device casing with a ceramic coating on the surface and a manufacturing method thereof. Background technique [0002] With the rapid development of wireless communication and information processing technology, portable electronic devices such as mobile phones and personal digital assistants (PDA) are emerging, allowing consumers to fully enjoy the convenience brought by high technology anytime and anywhere. In addition to updating and expanding the functions of these portable electronic devices, they are constantly being updated in appearance and shape as they become popular and user preferences. [0003] There are two main types of portable electronic device casings at present. One is the metal casing, which has a relatively single color. Even if protective or decorative coatings such as baking varnish and electroplating are formed on the surface, it is often caused b...
