| Abstract: | In order to develop green manufacturing and microfabrication,an innovative electrochemical machining method was introduced,that is the electrochemical machining(ECM)technology in ultra-pure water.The relative relationship of water dissociation and current density under the function of strong acid cation exchange membrane was studied,and the mechanism of electrochemical machining in ultra-pure water was also explored.On the basis of theoretical analysis,the significance of two turning points of the voltage-current density characteristic curve was presented.As the result of water dissociation and machining experiments,the factors affecting current density were determined. |
