用非晶合金作为磁芯制作涡流探头,运用正交试验设计方法,通过改变频率、磁芯直径、线圈匝数等参数对探头进行优化试验,对比各参数对探头检测灵敏度的影响。结果表明:设置合适的探头参数能够提高检测灵敏度;相同条件下非晶合金磁芯探头比铁氧体磁芯探头检测灵敏度要高。 Using an amorphous alloy as the core, an eddy current probe was fabricated. The orthogonal test design method was used to optimize the probe by changing parameters such as frequency, core diameter, number of turns and so on. The influence of each parameter on the sensitivity of the probe was compared. The results show that setting the proper probe parameters can improve the sensitivity of detection. The detection sensitivity of amorphous alloy magnetic core probe is higher than that of ferrite magnetic core probe under the same conditions.
