However, in ECM-based combined processes (such as electrochemical grinding (ECG), electrochemical discharge machining), both ECM and the other processes participate in material removal. The resulting synergetic effect is a 1+1=3 effect which implies that the combined effect of ECM with other process energy is more than double the benefits of ...

In electrochemical processes, an input of electrical energy drives CO 2 conversion reactions in an electrolytic cell in which CO 2 is reduced on the cathode while oxygen evolves at the anode. CO 2 can be converted to a range of fuels and fuel precursors by this means, including CO, formic acid (HCOOH), methane (CH 4 ), and ethylene (C 2 H 4 ).

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.
