Titanium Coils for Chromium Plating Baths Chromium-plating baths mainly consist of aqueous solutions of chromic acid with minor additions, e. g. of sulphuric acid, chromic sulphate, chromic chromate, or fluorsilicic acid. They are regarded as strong oxidation agents. The operating temperature is between room temperature and about 65°C. Chromium-plating equipment often consists of steel trays lined with wire-reinforced glass plates or with antimonious lead. In some cases, it is possible to use brick-lined trays. Due to the hi

Platinum Plated Titanium Anodes for Electroplating in Acidic Copper Sulphate Solution For a couple of years, gold-plating baths have been equipped with undissolvable anodes. Significant reasons for using undissolvable anodes are to avoid pollutions of the gold-plating bath by other metals from the gold anodes and to keep the current output at the anode and cathode possibly on the same level. Depending on the type of gold-plating bath you can use undissolvable anodes of stainless steel, graphite, nickel/ chromium alloys, or platinum

Why Platinum Plated Titanium Electrodes is Applied in the Electroplating Industry? The corrosion resistance of titanium is based on a stable self-curing oxide film on the metal surface which immediately develops in the air at normal or elevated temperatures. Titanium remains corrosion resistant as long as this oxide skin is maintained or constantly reproduced. However, this oxide skin, developing also on the metallic bright material, has a very high electric resistivity so that a charge exchange with the electrolyte cannot take pla

What Cause the Destruction of MMO Anodes? The lifetime of MMO anodes is affected by the electrocatalytic layer, which is conductive. It is corrosion resistance against the electrolyte like fluorides, bromides, cyanates, and nitrites. The roughness of this active coating layer affects the current density and kinetics of electrochemical reactions that in turn determine the operating potential of the electrode surface and the stability of the coating. Per MMO anode for oxygen evolution in acid solutions, the destruction of platinum
