Title: Experimental study on conductivity versus concentration of electrolytes for electrochemical deburring process
Biography: Alay Patel
Statement of the Problem: Electrochemical deburring (ECD) is a widely popular process among industries to manufacture miniature parts and intricate components. Hence, it is important to optimize its process parameters to obtain high material removal rates and cost efficiencies. The domain of this paper focuses on the electrolyte types and control over the variation of its concentration during ECD operations. Here, a technique is developed to maintain a set value of electrolyte concentration based on its relation with the electrical conductivity of electrolytes.
Methodology & Theoretical Orientation: Sample testing solutions were prepared in laboratory for the electrolytes, sodium chloride and sodium nitrate. Conductivity and total dissolved solids (TDS) measurements were taken for each sample and recorded. Standard conductivity and TDS versus concentration charts were prepared corresponding to the measurements. Then the charts are trend-fitted to obtain certain empirical relations for the concerned parameters. These relations are then used to identify the value of conductivity by substituting the desired amount of concentration.
Conclusion & Significance: The measured values of conductivity and TDS for various concentrations of sodium chloride and sodium nitrate show a proportionate growth with respect to the concentrations. The interpolation models obtained from the plots can be utilized in industrial ECD operations to control and manipulate concentration of electrolytes. As it is a difficult task to maintain a set value of concentration in such applications, this technique can simplify it by monitoring the corresponding value of conductivity for the required concentration.
