| Abstract: | The electroformed Ni-Mn alloys hold good prospects for its specific performance. In this study,based on the analysis of the principle of electrodeposited nanocrystalline materials,Ni-Mn alloys were electroformed by using strong flushing electrolyte,direct current,high frequency pulse current,and the additives added to the electrolyte. Mn content,the surface morphology and the grain size of the layers were tested. The results show that the grain sizes of the alloys are down to the order of nanometer. The effect of Mn content,current density,the additives,etc.,on grain size and surface morphology of the alloy layer has been discussed. |
