| 中文摘要: |
| 为了研究间歇交变磁场频率对堆焊层金属组织及性能影响，对低碳钢表面进行等离子弧堆焊时外加间歇交变纵向磁场，并利用光学金相、X射线衍射、显微硬度和湿砂橡胶轮磨损试验等方法系统分析了不同磁场频率对等离子弧堆焊试件的影响。结果表明：适当的交变磁场频率能有效地增加堆焊金属中硬质相的数量，控制硬质相的生长方向，提高堆焊层金属的硬度和耐磨性，从而进一步获得最佳的电磁搅拌效果。 |

| In order to research the influence of frequency of intermittent altemative magnetic field on micro structure and properties of plasma arc surfacing layer, a longitudinal intermittent alternative magnetic field has been applied to the plasma arc surfacing welding on low carbon steel. The effect of different frequencies of magnetic field on the hardness , wearing resistance and microstructure of surfacing layer have been systematically researched by using optical e lectronic microscope, wear test and microscopic hardness testing. The results have indicated that proper frequency can increase the amount of hardening phase in overlay deposit, control the growth direction of hardening phase and improve the hardness and wear resistance of the surfacing overlay. Moreover, the optimum effect on electromagnetic stirring can be obtained. |
