摘　　要：使用普通电火花机床进行沉积时会出现加工工件表面沉积层厚度较小、表面粗糙度值较大的问题,针对上述问题做了大量实验研究。基于电火花沉积理论,提出采用永磁磁场与电火花复合沉积的方法,通过永磁场的作用,使铁磁工件材料磁化,从而使铁磁材料因受到一个向下的磁场力而难以脱离工件表面,这样可以使得工件表面沉积层的厚度增大,表面粗糙度值降低,进而提高材料的利用率。The problem of deposition coating is that the sedimentary thickness is small and the surface roughness is big by ordina- ry EDM tool,lots of experimental research have done to solve this problem. Present a new depositing method by compounding per- manent magnetic and EDM based on the theory of electric spark deposition. Through the role of permanent magnetic field, the magnetic workpiece is magnetized, so the magnetic materials receive a downward force thus making them difficult to deviate from the workpiece surface, this can make the thickness of sediment increased,the surface roughness reduced and the utilization factor of material increased.
