| 摘 要： | 对低碳钢表面进行钴基等离子弧堆焊时外加纵向磁场,发现当磁场强度和焊接工艺参数相匹配时,焊缝组织才能获得最佳的细化效果,并着重分析了磁场强度和焊接电流对钴基合金堆焊层硬度和耐磨性的影响.结果表明,引入适当的外加磁场不仅可以细化堆焊层金属组织的晶粒,而且能够改善堆焊层金属的硬度和耐磨性,从而提高堆焊层金属的综合力学性能.

| Abstract: | The effect of applied longitudinal magnetic field on Co-based plasma arc surfacing on low carbon steel was studied.It is found that only the magnetic intensity and weld criterion parameters must be matched properly,the optimal effect of grain refining can be gained.And the discussed emphasis is the influence of magnetic density and welding current on the regularity of hardness and wear resistance of the overlay welding metal.The result indicated that proper electromagnetic field can refine the structure of overlay weld metal but also improve the hardness and wear resistance of the overlay welded mental,which increase the comprehensive mechanical properties of overlay welded metal. |
