Abstract

The invention discloses a novel 38CrMg2NiA alloy corrosion solution which is prepared by adding certain amounts of hydrochloric acid, potassium hydroxide and alcohol to distilled water, wherein the volume percentage of the hydrochloric acid is 1.5%, the volume percentage of the potassium hydroxide is 4.5%, the volume percentage of the alcohol is 20% and the balanced is the distilled water. The hydrochloric acid is firstly added, the potassium hydroxide is then added and finally the alcohol is added. The corrosion solution enables metallographic corrosion of the 38CrMg2NiA alloy to be as easy and quick as that of aluminum alloy. The corrosion solution is saved in cost and is especially suitable for corrosion of the 38CrMg2NiA alloy.

Description

technical field [0001] The invention relates to a novel 38CrMg2NiA alloy corrosion solution, which belongs to the technical field of corrosion solutions. Background technique [0002] The metallographic structure of 38CrMg2NiA alloy is difficult to corrode, even if it is corroded, its structure is often not completely displayed, 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 38CrMg2NiA alloy as simple and fast as that of aluminum alloy is a difficult problem to be solved. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a novel 38CrMg2NiA alloy corrosion solution, through which the metallographic structure of the 38CrMg2NiA alloy can be directly observed without anodic coating treatment and polarized light observation, so...
