| titleOfInvention | Method of etching boron steel surface for watching austenite grain formation |
| abstract | The present invention relates to a corrosion method of a boron steel which enables a surface of a boron steel containing boron in a range of 0.08 to 0.50% based on the total weight to be corroded to observe austenite crystal grains. The corrosion method of the present invention comprises: 30 to 40 g of a picric acid salt as a sugar corrosion inhibitor, 35 to 40 g of copper chloride as a coloring agent, and 40 to 50 g of a sodium salt of dodecylbenzene sulfonic acid as a surfactant are dissolved to prepare a corrosive liquid; A corrosion step in which the surface of the specimen is corroded by immersing the boron steel specimen in the corrosion solution prepared in the corrosion solution preparing step; And a cleaning step in which the surface-corroded boron-steel specimen is taken out of the caustic solution and cleaned. |
