Embodiment Construction

[0027] In order to better illustrate the present application, the following will be described in detail through the embodiments in conjunction with the accompanying drawings.

[0028] refer to Figure 1-Figure 3 , the metal part 10 of the present application includes a surface 12 and another surface 14, and the metal part 10 treated on the first surface 12 can be used as an appearance part of any end product. In this embodiment, the method includes the following steps:

[0029] S101: contact with an aqueous solution containing at least one compound of ammonia, methylamine, hydrazine, and ethylenediamine, or use laser engraving to form nanopores 122 on one surface 12 of the metal piece 10 .

[0030] During the contact process between the first surface 12 of the metal piece 10 and the aqueous solution comprising at least one compound of ammonia, methylamine, hydrazine and ethylenediamine, the aqueous solution has a slight corrosion effect on the first metal surface 12, and can ...

Abstract

The invention discloses a metal part surface treatment method. The method comprises the following steps that a water solution at least including at least one or more compounds in ammonia, methylamine,hydrazine and ethanediamine is adopted for contact, or laser engraving is adopted for forming nanopores in one surface of a metal part; a decoration layer is applied to the surface of the metal part;and at least one part of the decoration layer is inlaid in the nanopores. According to the above scheme, the nanopores are formed in one surface of the metal part, then at least one part of the decoration layer formed on the surface of the metal part can be inlaid in the nanopores, and the binding force of a decoration film and the metal surface is greatly enhanced. The invention further providesa metal shell and a terminal including the shell.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a method for surface treatment of metal parts, a metal shell and a terminal. Background technique [0002] With the continuous improvement of users' requirements for the appearance and texture of products, more and more portable terminals, such as mobile phones and tablet computers, use metal casings. In order to make the metal casings have a better appearance, paint or Apply a decorative film, etc. However, the bonding force between the metal shell and the paint layer or the decorative film is not strong, and after a period of use, the paint is prone to peeling off, or the part of the film is peeled off. Contents of the invention [0003] The main technical problem to be solved by this application is to provide a metal surface treatment method, a metal casing and a terminal, which can solve the existing problem of weak bonding between the metal casing and the ...
