交流接触器铁芯主要失效形式是在小能量多次冲击负荷及交变磁力作用下的接触端面表层冲击接触疲劳剥落。对铁芯接触端面进行５７０℃软氮化处理２ｈ，其使用寿命可提高１倍以上。
AC contactor core failure is the main form of small energy multiple impact load and alternating magnetic contact surface under the impact of contact fatigue spalling. The iron core contact end face 570 ℃ soft nitriding 2h, its service life can be increased more than 1 times.
