A kind of aluminum alloy chemical milling solution and process

Abstract

The invention discloses an aluminum alloy chemical milling solution. The main components of the chemical milling solution are sodium hydroxide, triethanolamine, sodium sulfide and OP-10 emulsifier. The steps of the chemical milling processing method are: (1) chemical degreasing; (2) alkali corrosion; (3) deoxidation; (4) glue coating; (5) chemical milling processing. The advantages of the present invention are: adding the additive OP-10 emulsifier in the alkaline chemical milling fluid can reduce the surface tension of the solution, make the contour line of the aluminum alloy chemical milling part smooth and smooth, and the arc transition part between the matrix and the chemical milling area is smooth , there will be no ripple phenomenon.

Description

A kind of aluminum alloy chemical milling solution and technology field [0001] The present invention relates to the field of chemical milling of metals, particularly the chemical milling of aluminum alloys. Background technique Aluminum alloy is a general term for alloys based on aluminum, and its main alloy elements are copper, silicon, magnesium, zinc, manganese, and secondary alloy elements Known as nickel, iron, titanium, chromium, lithium and so on. Aluminum alloy is the most widely used non-ferrous metal structural material in industry. It has been widely used in aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the development of science and technology and industrial economy in recent years With the rapid development, the demand for aluminum alloy welded structural parts is increasing day by day, so that the research on the weldability of aluminum alloy is also in-depth. aluminum The density of the alloy is low, but th...
