The Selectron process is a special method for the selective rework and repair of damaged surface coatings. In this tampon-electro-plating method the electrolyte is distributed in a piece of cotton which is wrapped around a graphite anode. The part to be plated represents the cathode, just as in the bath-based plating method. If the anode is positioned on the work piece, selective layers are deposited when a voltage is applied.

The Selectron process technology is suitable for many applications. This method is highly successful and cost-effective especially for hydraulic and printing cylinders as well as in the heavy mechanical engineering industry. The process also fulfils specifications as for example MIL Standard 865c (military technology), Naviships 0900-038-6010 (ship constructions) or QQ 416a (aviation).
