Electrolytic polishing provides less deformation with edge rounding and possible washout of phases. The principle of electrolytic etching is the same as that of chemical etching, except that the specimen is placed as an anode in a galvanic cell, resulting in the removal of material from the specimen surface.

Cleaning welds manually may appear to be the cheapest and most affordable way to clean your welds, but it's far from the most effective. Electrochemical weld cleaning is a process used in the manufacturing industry to remove post-weld impurities such as heat tint, discoloration, and surface rust using an electrical current and electrolytic fluids.

W. Brian Rowe, in Principles of Modern Grinding Technology (Second Edition), 2014. 6.5 Creep-Feed Grinding. Creep-feed grinding developed about the same time as high-speed grinding. Conventional grinding uses high work speeds and very small depth of cut. The concept with creep-feed grinding is to slow the work speed right down to allow deep ...
was previously accomplished by conventional milling. Work hardening, resulting in high tool breakage, was a common problem. Average required machining time was 25 - 50 hr. An additional 3-5 hr handwork was spent for deburring the slots. Electrolytic grinding now accomplishes this job in Fig. 2 - Principle of electrochemical grinding 2631
The working principle of Electrochemical grinding process was similar to Electrochemical Machining process to removal of material by means of electrically charged grinding wheel. Instead of tool, a grinding wheel was used in ECG. Material removed from the work piece was depends on electrolyte.
The working principle of electrolytic polishing is the same as the principle of chemical polishing. A dissolving material that uses a protruding part is applied on the selective surface of the metal. Nevertheless, if compared with the chemical polishing, the effect of the cathode reaction can get easily eliminated, which is a much better option.
An electrolytic capacitor has one of the biggest capacitances compared to other capacitors. It is used in electrical circuits with a low frequency and high current, such as the circuits of a power-supply filter which have fluctuating currents and output voltage. If there are no rechargeable batteries present, then an electrolytic capacitor can offer the same kind of low-frequency electric ...
The working principle of electrochemical grinding is When a metal surface is acted upon with an electrolyte under a high current, the metal surface gets oxidized to form an oxide layer (corrosive layer). This layer is removed with the action of a flowing electrolyte and rotating grinding wheel.
