Abstract

An aluminum part surface microetching method, comprising the following steps: subjecting an aluminum part to pretreatment which involves successive degreasing, neutralizing and alkaline etching treatments; carrying out microetching on the surface of the aluminum part following pretreatment to form micropores on the surface of the aluminum part; subjecting the micropores formed on the surface of the aluminum part to washing and reaming treatments, wherein the microetching treatment involves placing the pretreated aluminum part in a microetching solution for microetching to be carried out, and the microetching solution comprises: 180g / L-200g / L of sulfuric acid, 150ml / L-500ml / L of microM. Further disclosed are an aluminum part composite and a production method therefor.

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...
