Abstract

The invention provides an aluminum member surface microetching method, an aluminum member complex and a preparation method thereof. The aluminum member surface microetching method comprises the following steps: performing pretreatment of oil removing, neutralizing treatment and alkali corrosion treatment in order on an aluminum member, microetching on the pre-treated surface of the aluminum member, forming micropore on the surface of the aluminum member; performing micropore washing treatment and pore enlarging treatment on the micropore formed on the surface of the aluminum member. The aluminum member complex comprises the aluminium member and a bonding member combined with the aluminum member, the aluminum member is processed by an aluminum member surface microetching method, the surface etched with the micropore is coated by a binder, and the aluminum member is bound with a plastic member or a resin piece. The aluminum member surface microetching method can generate various micropores on the surface of the aluminum member, and can effectively enhance the bonding strength between the aluminum member and other materials or the members such as resin or plastics.

Description

technical field [0001] The invention belongs to the technical field of materials, in particular to a method for microetching the surface of an aluminum part, an aluminum part composite and a preparation method thereof. Background technique [0002] With the development of electronic products in the world and the development of other industries that require lightweight materials such as the aviation industry, products are extending towards thinner and lighter. Therefore, there is an increasing demand for lightweight materials, but also higher requirements for the relevant mechanical properties of the corresponding materials. [0003] Among them, aluminum and its alloys are widely used due to their light weight and good mechanical properties. However, it still cannot meet the current pursuit of light and thin materials in related industries. In this context, metal composite materials came into being. [0004] A metal composite is a multiphase solid material that combines me...
