Electroplating is a process whereby a coating is deposited onto a substrate by passing a DC current between the anode and the cathode. The metal that is to be plated is dissolved in the electrolyte (carefully chosen to ensure anode passivation does not occur). The anode is anodically polarised and the cathode (the component to be electroplated) is cathodically polarised. This forms a closed cell. Anode performance is of considerable importance in realising the success of the electroplating industry.


Bornagodaz manufactures Mixed Metal Oxide (MMO) anode for use in various applications where the electroplating of a wide range of metals is necessary. The use of stainless steel anodes, although relatively inexpensive produce iron oxide (rust) as a by-product of anodic passivation and the use of graphite anodes results in an increasing inter-electrode gap as the anode dissolves meaning voltage and product quality do not remain constant.


The advantage that this MMO anode has over the two previous anode types and lead anodes is that the risk of additional toxic or hazardous substances being introduced into the electroplating line is eliminated, eradicating costs that arise from the removal of hazardous substances. It is also environmentally friendly and the fact that the inter-electrode gap remains constant throughout the design life of the anode means that the MMO anode maintain constant voltage and product quality. Oxygen-evolving MMO anode has lower anodic operating potentials and use of this anode yields the additional advantage of the ability to re-use the anode. Once the anode has reached the end of its design life the necessary repairs can be made, the anode can be cleaned and then re-coated.


Bornagodaz MMO anodes are extensively used in the electroplating of products from jewellery, to steel strip plating, to platinum plating and much more. We offer anodes for electroplating in various shapes and sizes suited to the application you.
