INFLUENCE OF THE INORGANIC SOLUTIONS ON THE CURRENT EFFICIENCY FOR IRON DISSOLUTION AT THE ELECTROCHEMICAL MACHINING
Keywords:
Electrolyte solution, anodic dissolution, electrochemical erosion, machining efficiency, inorganic solutions
Abstract
At the processing by electrochemical erosion, an important influence has the working solution (electrolyte). This paper presented the results obtained by applying inorganic solutions at the machining by electrochemical erosion. There are analysed the process which takes place into the electrolytes during the anodic dissolution of the metal, the current efficiency at H generation and iron dissolution, as well as the modification of the pH values. By comparing the obtained results has been established the best results for processing by electrochemical erosion of steels alloyed with chrome.
