Expt 4: Study the effect of process parameters in electrochemical grinding: Less power is needed for ECG than for ECM since the machining area is smaller and the abrasive in the wheel removes the oxide film from the surface of the workpiece. - cathode is an electrically conductive abrasive grinding wheel.
ECG • Electrochemical grinding (ECG) is an electrolytic material-removal process involving a negatively charged abrasive grinding wheel, a conductive fluid (electrolyte), and a positively charged work piece. • Work piece material corrodes into the electrolyte solution. ECG is similar to electrochemical machining except that the cathode is a specially constructed grinding wheel …
Thin-walled iron parts are easily deformed by traditional mechanical processing methods due to the poor rigidity. Besides, it is well known that the cutting tools suffer serious wear when machining pure iron materials. In this paper, a series of experiments were carried out to explore the performance of electrochemical grinding (ECG) method on machining pure iron …

E. Allahkarami et al. 30 Such interactions occur whenever two or more sulphide minerals (or a sulphide mineral/grinding media) are in contact. The electrochemical reactivity is indicated by the rest potential of the sulphide mineral, .e. the higher i the rest potential, the nobler it is and the less active in thermodynamic sense.

The pulverization of silicon during lithiation/delithiation due to its huge volume change results in a loss of electrochemical activity. In this work, advantage is taken of the unavoidable pulverization and an innovative strategy of in-situ self-adapting electrochemical grinding (ECG) is designed for stable silicon anode.
To solve this difficult problem, this study proposes a novel method. of fabricating complex micro rotary structures by using wire electrochemical grinding. …

Electrochemical machining is a process of removing metal with the help of the electrolysis process. The electrochemical process is also known as the reverse of the electroplating process because, in electroplating, the metal is deposited on the surface of the workpiece, while in electrochemical machining the metal is removed from the workpiece.
In Electrochemical grinding, the metal bonded grinding wheel filled with a non-conductive abrasive. The grinding wheel act as a cathode and the workpiece is act as an anode. The electrolyte, which is usually sodium nitrate, sodium chloride, potassium nitrite, with a concentration of 0.150 to 0.300 kg/litre of water.
The metal cutting wastewater was treated with electrocoagulation (EC) and electrochemical-Fenton (EF) method in a bipolar trickle tower reactor. In EC treatment, the COD removal efficiency was obtained as 81.3% with 89.0 kWh/m3 energy consumption using 0.7 mA/cm2 current density and 0.2 mM Na2SO4. With the EF method, 99.2% COD removal was …
Electrochemical Machining (ECM) is a non-traditional machining (NTM) process belonging to Electrochemical category. ECM is opposite of electrochemical or galvanic coating or deposition process. Thus ECM can be thought of a controlled anodic dissolution at atomic level of the work piece that is electrically conductive by a
