低压电器电磁铁芯的表面化学热处理

Chemico-Thermal Treatment for Ironcore of Iow-Voltage Electric Appliance

在对低压电器电磁铁芯失效分析的基础上，对其接触端面进行表面化学热处理及铁芯使用寿命模拟试验。试验表明，软氮化处理可以明显提高其使用寿命。

Based on failure analysis of the iron core of low-voltage electric appliance,chemico-thermal treatment and analog test of service life for work face of the ironcore were studied.The results shown that service life of the nitrided ironcore have been extented obviously.
