Embodiment Construction

[0021] In order to make the above and other objects, features, advantages and embodiments of the present invention more comprehensible, this specification will specifically cite a series of embodiments for illustration. However, it should be noted that these examples are only used to illustrate the implementation of the present invention, rather than to limit the present invention.

[0022] Figure 1A It is a flow chart of steps of a metal surface patterning method according to an embodiment of the present invention. Firstly, step S101 is to provide a metal substrate, and the metal substrate is aluminum or aluminum alloy. However, suitable materials for the above-mentioned metal substrates may be other metal materials, such as magnesium, titanium or titanium-magnesium alloys.

[0023] Next, step S103 is to clean the metal substrate with a chemical or physical treatment. The above chemical treatment includes using a neutral or alkaline chemical solution, such as acetone to cle...

Abstract

The invention provides a method for patterning a metal surface. The method comprises the following steps of: firstly, cleaning a metal substrate by chemical or physical treatment and polishing the metal substrate; secondly, performing anodic oxidation treatment on the metal substrate so as to form a porous oxide film on the surface of the metal substrate, wherein the porous oxide film is provided with a plurality of pores with the pore diameters of between 20 and 400 nanometers; thirdly, providing a pattern layer and absorbing ink particles into the pores of the porous oxide film in a printing mode, wherein the particle sizes of the ink particles are between 10 and 300 nanometers; and lastly, sealing the pores so as to form a pore sealing layer which is continuously covered on the surface of the porous oxide film.

Description

technical field [0001] The invention relates to a metal surface patterning method and its structure, and in particular to a single anodic oxidation treatment method for the metal surface. Background technique [0002] Generally speaking, most electronic devices use plastic as the basic material, but for today's consumers, in addition to practical and functional requirements, electronic devices are gradually beginning to pay attention to metal textures. Metal casings are becoming the mainstream for more expensive electronic products. The use of metal materials has the following advantages: good electromagnetic shielding effect, good heat dissipation, good rigidity, impact resistance, etc., strength protection and recyclable environmental protection characteristics. [0003] In order to change the surface properties of the metal casing, for example, to give the metal appearance a variety of colors and retain the texture of the metal appearance, and to prevent rust or abrasion...
