渗碳、渗氮、碳氮共渗、渗硼、渗铝和渗铬等化学表面处理可提高零件的使用性能。为保证各种工艺的表面处理的质量 ,必须对经表面处理后的零件进行显微组织检查 ,其中金相法是广泛采用的重要检测手段 ,而组织显示是金相方法中的重要步骤。下表所列为常用的渗层组织侵蚀剂和侵蚀 Carburizing, nitriding, carbonitriding, boronizing, aluminizing and chromizing chemical surface treatment can improve the performance of parts. In order to ensure the quality of the surface treatment of various processes, the microstructures of the surface-treated parts must be examined. The metallographic method is an important detection method widely used, and the tissue display is an important step in the metallographic method. The following table lists commonly used disseminated etchants and erosion
