一种解决金属裂纹在腐蚀剂腐蚀后返酸问题的方法
摘要：
本发明公开了一种解决金属裂纹在腐蚀剂腐蚀后返酸问题的方法，其特征在于，将金属试样加工成金相试样后，进行磨抛，以达到腐蚀的要求；磨抛后的金相试样经酸性腐蚀剂进行腐蚀后，立即浸入专用试剂，再用超声波振荡仪振荡金相试样2-10分钟；将金相试样取出，用清水清洗1-2分钟，再用酒精冲洗后，用吹风机吹干即可。本发明提供的方法可以很好地解决金相试样在腐蚀剂腐蚀后裂纹中的返酸问题，有利于材料检测分析工作，适用于碳钢和合金钢等金属材料。
摘要（英）：

The invention discloses a method for solving the problem of acid returning permeation of metal cracks subjected to corrosion of corrosives. The method is characterized by comprising the steps of polishing a metal sample processed into a metallographical sample to meet requirements of corrosion; immersing the polished metallographical sample subjected to the corrosion of the acidic corrosives immediately in a special reagent, and utilizing an ultrasonic vibration meter to perform vibration on the metallographical sample for 2-10 minutes; and taking the metallographical sample out, cleaning the metallographical sample through water for 1-2 minutes, washing the metallographical sample through alcohol, and then drying the metallographical sample through a drier. The method can solve the problem of the acid returning permeation of the metal cracks subjected to corrosion of the corrosives, facilitates material detection and analysis, and is suitable for metal materials such as carbon steel and alloy steel.
