Summary:A corrosion method for rapidly displaying a composite interface of a laminated steel plate is characterized by comprising the following steps: (1) preparing a sample; (2) preparing a corrosive agent; and (3) corroding the sample. The corrosive agent comprises water, nitric acid and hydrochloric acid according to the volume ratio of 1: (4-6): (8-10). The corrosive agent has the advantages of few types of used chemical reagents, easily available raw materials, simple preparation method and process, extremely easy operation of the corrosion method, and good display effect. According to the corrosion method, the position of the composite interface of the ply-rolled extra-thick steel plate can be rapidly and effectively determined, the accuracy of the detection result of the extra-thick steel plate can be improved, follow-up production organization optimization is guided, and the structure performance research analysis characterization efficiency can be improved. The corrosion method is suitable for being widely p
