Embodiment
[0018] A new type of 35Cr2MnSiC steel corrosion solution, using mixed acid as raw material, was prepared by a conventional solution preparation method. In 79.1mL of distilled water, a volume of 5.8mL of nitric acid, 9.6mL of hydrochloric acid and 5.5mL of hydrofluoric acid were added successively, and then Stir well with a glass rod.
[0019] The corrosion solution prepared by the above steps is used to corrode 35Cr2MnSiC steel, the specific effect is shown in figure 1 and figure 2 , figure 2 Corrosion effect diagrams using other common corrosion solutions show that the corrosion solution of the present invention has a better effect.

The invention discloses a novel corrosive solution for 35Cr2MnSiC steel. The preparing method of the novel corrosive solution for the 35Cr2MnSiC steel comprises the step that the components including, by volume fraction, 5.8% of nitric acid, 9.6% of potassium hydroxide and 5.5% of alcohol are added into balance distilled water in the adding sequence that the nitric acid is added firstly, then the potassium hydroxide is added, and the alcohol is added finally. By the adoption of the prepared novel corrosive solution for the 35Cr2MnSiC steel, the metallographic-phase corrosion of the 35Cr2MnSiC steel can be made as easy and rapid as that the aluminum alloy, and cost is saved; the novel corrosive solution can be widely applied to corrosion of the 35Cr2MnSiC steel.
Description
technical field [0001] The invention relates to a novel 35Cr2MnSiC steel corrosion solution, belonging to the technical field of corrosion solutions. Background technique [0002] The metallographic structure of 35Cr2MnSiC steel 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 35Cr2MnSiC steel 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 by the present invention is to provide a novel 35Cr2MnSiC steel corrosion solution, which can directly observe the metallographic structure of the 35Cr2MnSiC steel after being corroded without anodic coating treatment and polarized light observation,...
