Abstract

The invention discloses a novel series-eight aluminum alloy (Al-Li) corrosion solution. The novel series-eight aluminum alloy (Al-Li) corrosion solution comprises mixed acid and is characterized in that the mixed acid is formed by adding a certain amount of hydrofluoric acid, a certain amount of hydrochloric acid and a certain amount of nitric acid into distilled water. According to the mass percentage, 4 ml of HF, 3 ml of HNO3 and 3 ml of HCl are added into 90 ml of distilled water.

Description

technical field [0001] The invention relates to a novel eight-series aluminum alloy (Al-Li) corrosion solution. Background technique [0002] The metallographic structure of the eight-series aluminum alloy (Al-Li) is difficult to corrode, and even if it is corroded, the structure is often displayed incompletely. Therefore, the metallographic structure of the eight-series aluminum alloy (Al-Li) is usually observed by anodic coating and polarized light. But this observation method is not only time-consuming, but also increases the production cost. Therefore, how to make the metallographic corrosion of eight-series aluminum alloys (Al-Li) as simple and fast as aluminum alloys is a difficult problem to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel eight-series aluminum alloy (Al-Li) corrosion solution to solve the problem of inefficient corrosion of eight-series aluminum alloys (Al-Li) in the pr...
