Embodiment 1
[0083] (1) Preparation for electrolysis
[0084] The steel ingot to be characterized is sectioned on a symmetrical plane, and on the obtained section according to Figure 4 Indicating sampling, the sample is required to be in the shape of a cuboid, with a thickness of 10mm and a length and width of 100mm. A total of 3 groups of samples are taken, which are marked as A, B, and C. Each group takes 6 samples, which are respectively recorded as A1~A6, B1~B6, C1~C6. Drill 3 M5 screw holes with a depth of 15mm at equal distances on one side of each sample to prepare bolts for hanging. The surface of the sample is required to be smooth, oil-free, and rust-free. The electrolyte solution is composed of tetramethylammonium chloride 2wt%, acetylacetone 8wt%, glycerin 5wt%, triethanolammonium 6wt%, and the rest is methanol with a purity of 99.9%.
[0085] (2) Electrolysis
[0086] Take the sample as the anode and the barbed wire as the cathode, adjust the electrolysis potential to 1.5-...
