1. What is Electrochemical Equivalent?

The Electrochemical Equivalent is the mass of a substance produced at the electrode during electrolysis by one coulomb of charge. It represents the amount of material removed or deposited per unit charge in electrochemical processes.

2. How Does the Calculator Work?

The calculator uses the electrochemical equivalent formula:

\[ e = \frac{Zr \times \rho}{\eta_e \times I} \]

Where:

\( e \) — Electrochemical Equivalent (kg/C)
\( Zr \) — Metal Removal Rate (m³/s)
\( \rho \) — Work Piece Density (kg/m³)
\( \eta_e \) — Current Efficiency (decimal)
\( I \) — Electric Current (A)

Explanation: The formula calculates the mass of material removed per coulomb of charge based on the volumetric removal rate, material density, current efficiency, and applied current.

3. Importance of Electrochemical Equivalent

Details: Accurate calculation of electrochemical equivalent is crucial for predicting material removal rates in electrochemical machining processes, optimizing process parameters, and ensuring dimensional accuracy in manufactured components.

4. Using the Calculator

Tips: Enter metal removal rate in m³/s, work piece density in kg/m³, current efficiency as a decimal (0-1), and electric current in amperes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for electrochemical equivalent values?
A: Electrochemical equivalent values typically range from 10⁻⁸ to 10⁻⁶ kg/C, depending on the material and process conditions.

Q2: How does current efficiency affect the electrochemical equivalent?
A: Lower current efficiency reduces the effective electrochemical equivalent as less material is removed per unit charge due to side reactions and inefficiencies.

Q3: Can this formula be used for electrodeposition processes?
A: Yes, the same principle applies to electrodeposition where material is added rather than removed, with appropriate sign conventions.

Q4: What factors influence metal removal rate in electrochemical machining?
A: Metal removal rate depends on current density, electrolyte composition, tool-workpiece gap, and material properties.

Q5: How accurate is this calculation for industrial applications?
A: While the formula provides a good theoretical estimate, actual industrial processes may require empirical corrections for factors like electrolyte flow, temperature, and surface finish requirements.
