Description

technical field [0001] The invention belongs to the chemical cutting technology and relates to a method for measuring the aluminum content in an aluminum alloy alkaline chemical milling solution. Background technique [0002] Chemical milling is an important aluminum alloy processing method widely used in aviation and aerospace industries, and it is now used by many OEMs. The chemical milling process can replace some mechanical processing and corrode excess metal from the surface of the part to change its size and reduce its weight. In addition, when mechanical processing cannot be achieved and chemical milling can meet the design requirements of the part, this method can also be used. Process processing, such as hyperboloids, large-area thin plate parts, and other complex parts can all use chemical milling. At present, chemical milling is an important processing method in domestic aviation main engine factories. The quality of chemical milling of parts depends on the qual...
