| Abstract: | The electroformed Ni--Mn alloy has agood application foreground because of its specific perfor-mance. In this paper, pulse electroforming of Ni--Mn al-loy was tested by using the device with flushing elec-trolyte. Mn content, the crystallite size and microhard-ness of the electroformed alloy layers were tested. Theresults show that the grain sizes of the layers are reduceddown to the order of nanometer. The effects of currentdensity and pulse parameters on Mn content, the grainsize and microhardness of the layers have been discussed. |
