电磁场作用下的铸铁表面重熔强化

The effect of electric magnetic field on cast iron surface remelting and harding

这里以铸铁HT2 0 0为目标 ,通过一系列试验 ,研究了在铸铁钨极氩弧局部重熔强化过程中 ,外加磁场对重熔层硬度及耐磨性的影响。试验结果表明 :磁场对铸铁局部重熔强化具有显著的作用。

The effect of magnetic field on hardness and wear resistibility of grey cast iron HT200 remelting harding surface with TIG arc was studied.The results show that magnetic field has remarkable effect on cast iron surface remelting and harding.
