| Abstract: | The functions of phosphorus acid,sulfur acid and cheese anhydride in electrolyte for electrochemical polishing were stated in this paper.Using stainless steel as research object,the inefficacy of electrolyte solution was analyzed by investigating the changes of concentration of Fe3+ and Cr3+ as a function of current density.The influence of each ingredient in the elecrolyte on polishing effeciency was analyzed,moreover,the index of judging the inefficacy of the electrolyte and the relevant measuring method were obtained,the control range of three ingredients was also detemined.It is important to control technical process so that to guarantee the quality of electrochemical polishing. |
