Stainless steel of 316/316 L is commonly used for the cathode plates, based on the development in the last decade. The electrolyte can be very aggressive for many stainless steel grades. As the investigated in this case, cathode plate made of 316 L had severe corrosion attacks such as pitting corrosion.
In the current study, nickel alloy C-2000, stainless steels 316L and 654SMO, and grade 2 titanium were for the first time critically evaluated as potential cathode materials for EDRR. The particular emphasis was placed on better understanding of the effect of cathode substrate on the overall efficiency of the gold recovery process.
A method of reducing the overvoltage of an industrial electrolyser cathode during electrolysis of brine while maintaining resistance of the cathode to corrosion, the method comprising employing a stainless steel cathode comprising less than about 6% by weight nickel wherein the surface of the stainless steel cathode has been roughened to a surface roughness Rq between about 1.0 and 5.0 ...

23-02-2021· Method of Pickling Passivation. According to the different operation mode, there are six methods for stainless steel pickling passivation, including paste method, brush coating method, spraying method, circulation method and electrochemical method. 1) Impregnation Method: This method is suitable and effective for stainless steel pipe, elbow and ...
Stainless steel is a corrosion resistant material having a wide range of uses, but also as a cathode of the copper electrolytic refining - can be used in the copper electrolytic refining process ISA method and KIDD method. However, when the system of stainless steel where the presence of aggressive anions (such as Cl - ), stainless steel occurs pitting corrosion, and thus lead to very serious ...
Permanent cathode electrolytic method is mainly used for metal electrolytic refining. Electrolysis is using the oxidation - reduction reaction principle, the Cu2 positively charged, flow to the cathode, electrolyte enrichment, at the cathode reduction for copper, adsorption on the cathode, cathode …
