摘要
针对武器装备零部件在役时出现微损伤的特点,就超声波、涡流、金属磁记忆三种无损检测方法加以对比分析如何检测微裂纹以及各自的优缺点。通过分析,得出检测大型部件表面和近表面缺陷时,选用涡流或超声波检测方法,检测埋深较大的内部微裂纹时,应用超声波进行定位定量检测;对于异型、高温零部件最好选用涡流非接触检测;检修武器装备时,先用磁记忆技术诊断,在发现有微裂纹微拟伤部位再用超声波进行量检测分析,超声波无法检测的情况下,可用射线检测。
For the character of crack in parts of weapon, this article introduces the methods of UT,ET and MT to test the crack, and contrasts their advantages and disadvantages. By analysis, ET or UT is suitable for testing surface and near surface crack of large parts, and UT is suitable for internal tiny crack. For the different type and high temperature parts, ET should be chosen. For the weapon parts, MT should firstly be use, and then UT and RT are used to test and analyse the crack.
