一种显示珠光体钢实际晶粒度的腐蚀剂
摘要：
本发明涉及金相腐蚀剂，公开了一种显示珠光体钢实际晶粒度的腐蚀剂，包括饱和苦味酸、苯磺酸、盐酸和水，其质量百分比为：30-70%的饱和苦味酸，10-15%的苯磺酸，10-20%的盐酸，余量为水。通过本发明的配比以及制备方法制备的金相腐蚀剂可使珠光体钢的晶界得到清晰的显示，尤其是对亚共析钢有很好的效果。
摘要（英）：

The invention relates to a metallic-phase corrosive agent and discloses a corrosive agent for displaying the actual grain size of pearlitic steel. The corrosive agent comprises the following components in percentage by mass: 30-70% of saturation picric acid, 10-15% of benzenesulfonic acid, 10-20% of hydrochloric acid and the balance of water. The metallic-phase corrosive agent prepared by the preparation method disclosed by the invention can be used for clearly displaying the grain boundary of pearlitic steel, and especially has good effects on hypoeutectoid steel.
