摘要
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。
The main failure form of the AC contactor ironcore is the contact fatigue peeling of the contact surface under the cyclic small energy impact and alternative magnetic force.The service life of the AC contactor ironcore was doubled after its contact surface was treaded by nitriding at 570℃ for 2h.
