A method for etching the prior austenite grain size of a high carbon pearlitic rail

This invention discloses a corrosion method for high-carbon pearlitic steel rails with a pre-austenite grain size. The sample test surface is polished, and during corrosion, the polished surface is completely immersed in the corrosive agent, taking care not to touch the bottom of the container to avoid affecting the corrosion effect. The corroded surface is observed periodically during corrosion. Once the corroded surface exhibits a uniform dark gray frosted state, it is removed, rinsed, and dried. Finally, excess corrosion layer is lightly polished on a polishing machine before observation. The corrosive agent includes hydrochloric acid, acetic acid, ferric chloride, benzalkonium bromide, shampoo, and deionized water. The purpose of this invention is to provide a corrosion method for high-carbon pearlitic steel rails with a pre-austenite grain size that can clearly display the pre-austenite grain boundaries, solving the problem of difficult corrosion of pre-austenite grains. Furthermore, the reagents used are stable, safe, and easy to store.
