Abstract

The invention discloses an etchant solution for Al-4.5Mg-Zr-Si-Ce alloy. Mixed acid is made by adding a certain amount of hydrofluoric acid, hydrochloric acid and nitric acid into distilled water. The mixed acid comprises, by volume, 3% of the hydrofluoric acid, 4.4% of the hydrochloric acid, 2.6% of the nitric acid, and the balance the distilled water. Besides, the nitric acid, the hydrochloric acid and the hydrofluoric acid are added in sequence. Through the manufactured etchant solution, metallographic etching of the Al-4.5Mg-Zr-Si-Ce alloy is made to be simple and fast, the cost is reduced, and the etchant solution is especially suitable for etching of the Al-4.5Mg-Zr-Si-Ce alloy.

Description

technical field [0001] The invention relates to an Al-4.5Mg-Zr-Si-Ce alloy corrosion solution, belonging to the technical field of corrosion solutions. Background technique [0002] The metallographic structure of Al-4.5Mg-Zr-Si-Ce alloy is difficult to corrode, even if it is corroded, its structure is often displayed incompletely, so the metallographic structure 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 Al-4.5Mg-Zr-Si-Ce alloy simple and fast is a difficult problem to be solved. Contents of the invention [0003] The technical problem to be solved in the present invention: provide a kind of Al-4.5Mg-Zr-Si-Ce alloy corrosion solution, the grain boundary and the grain display of Al-4.5Mg-Zr-Si-Ce alloy after corrosion are clear, to overcome the existing There are technical deficiencies. [0004] Technical ...
