根据修理需要,进行飞机框板原位带漆涡流检测的可行性研究。试验方面,首先确定对比试样,选择代替漆层的非导电弹性膜片,由此确定检测频率;理论分析方面,确定允许带漆检测的漆层厚度和带漆检测时能有效检出的最小缺陷当量;最后以带自然缺陷的零件为例,对研究结果进行了试验验证,确保了带漆涡流检测的可行性。 According to the need of repairing, the feasibility study of the in-situ paint eddy current testing of aircraft frame plate was carried out. In the aspect of experiment, firstly, the contrast sample is selected, and the non-conductive elastic film instead of the paint layer is selected to determine the detection frequency; in the theoretical analysis, the minimum allowable thickness of the paint layer to be tested with the paint and the paint can be detected Defect equivalent; Finally, taking the parts with natural defects as an example, the experimental results were verified by experiments to ensure the feasibility of the paint-based eddy current testing.
