Problems solved by technology

However, the magnesium metallization in magnesium alloys is active, and it is generally not easy to deal with the electroplating procedures on the surface of magnesium alloys.
Therefore, the surface of magnesium alloy must be passivated first, and the process is more complicated.

Abstract

The invention discloses a double-metal bonding method and structure. The method comprises the following steps that one machined and formed aluminum piece is provided; the machined and formed aluminum piece is placed in a die-casting die, the machined and formed aluminum piece is coated with one magnesium metal liquid, die-casting forming is carried put, the magnesium metal liquid forms one magnesium metal piece, and the magnesium metal piece and the machined and formed aluminum piece are clamped in a clamping and hooking mode; and after the magnesium metal piece and the machined and formed aluminum piece are combined, coating protection is carried out on the magnesium metal piece and the machined and formed aluminum piece, one structure is machined in the machined and formed aluminum piece, and highlight treatment and anodic oxidation are carried out in the structure. According to the double-metal bonding method and structure, the structural inner wall of the aluminum piece or an aluminum metal piece is machined and formed through highlight treatment, and a smooth surface can be obtained after double-metal combination, so that time-consuming grinding is reduced, and surface shrinkage limit and air holes are reduced; and according to the double-metal bonding method and structure, the purpose of double-metal combination can be achieved in a mode of direct connection of plastic or a surface nano structure or double metal.

Description

technical field [0001] The invention relates to a double metal combination method and its structure. Background technique [0002] A housing or housing for an electronic device may include multiple structural components. For example, a notebook computer may include a display, a main body, etc., the display further includes an upper cover and a display main body, and the main body may include a keyboard cover and a bottom structure. The aforementioned body or cover may comprise various suitable materials. [0003] The shell or shell of electronic equipment, such as the shell of portable electronic equipment, has a very high chance and frequent contact with other objects (such as desktops, hands, ground, magnesium alloy objects, etc.) to cause deformation of the shell or shell. Because the shell or shell is worn or painted or the protective layer is damaged due to collision or friction, the metal object of the shell or shell body is rusted and cannot be protected, and the ef...
