Abstract:

The possibility of using pulsed current in electrochemical machining at low electrolyte flow rate has been investigated. Theoretical aspects of predicting electrolyte heating and limiting rate of mass transport are discussed in terms of simplified models. High rate dissolution of nickel in sodium chloride solutions under pulsed current conditions was investigated in a flow channel cell by studying the influence of different pulse parameters on anode potential, surface microtexture, surface roughness and current efficiency of metal dissolution. Obtained results indicate that anode potential and surface finish are controlled by mass transport in agreement with steady state behavior. Maximum current density applicable under pulsed current conditions is limited by the occurrence of sparking.
