Embodiment
[0013] A new type of 45CrNi4VA steel corrosion solution, using mixed acid as raw material, is prepared by a conventional solution preparation method. 4.5ml of nitric acid, 8ml of hydrochloric acid and 2ml of alcohol are added to 85ml of distilled water, and then stirred evenly with a glass rod.
[0014] The corrosion solution prepared through the above steps is used to corrode 45CrNi4VA steel, see the specific effect figure 1 , it can be seen that the effect of the pure aluminum corrosion solution of the present invention is better.

The invention discloses novel 45CrNi4VA steel corrosion solution. The novel 45CrNi4VA steel corrosion solution comprises mixed acid; the mixed acid is prepared by adding a certain quantity of hydrofluoric acid, hydrochloric acid and alcohol in distilled water, wherein the volume fractions of the components are 4.5% of hydrofluoric acid, 8% of hydrochloric acid and 2% of alcohol; the balance is the distilled water; and the adding sequence of the components is nitric acid, hydrochloric acid and alcohol. The prepared corrosion solution can enable the gold phase corrosion of 45CrNi4VA steel to become simple and quick, saves the cost, and in particular, is suitable for the corrosion of the 45CrNi4VA steel.
Description
technical field [0001] The invention relates to a novel 45CrNi4VA steel corrosion solution, which belongs to the technical field of corrosion solutions. Background technique [0002] The metallographic structure of 45CrNi4VA steel is difficult to corrode, even if it is corroded, its structure is often displayed incompletely, so the metallographic phase 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 45CrNi4VA steel become 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 novel 45CrNi4VA steel corrosion solution, the metallographic structure of 45CrNi4VA steel can be directly observed after its corrosion without anodic coating treatment and polarized light observation, so that the metallographic cor...
