    Abstract: The present invention relates to a process for coating apparatuses and apparatus parts for chemical plant construction-which are taken to mean, for example, apparatus, tank and reactor walls, discharge devices, valves, pumps, filters, compressors, centrifuges, columns, dryers, comminution machines, internals, packing elements and mixing elements-wherein a metal layer or a metal/polymer dispersion layer is deposited in an electroless manner on the apparatus(es) or apparatus part(s) to be coated by bringing the parts into contact with a metal electrolyte solution which, in addition to the metal electrolyte, comprises a reducing agent and optionally the polymer or polymer mixture to be deposited in dispersed form, where at least one polymer is halogenated.

    Abstract: Process for coating components comprises electrolytically applying anode spheres to a flexible wire used as the anode. The spheres are made of a material having a high specific electrical resistance which guarantees a predetermined distance of the anode and/or anode spheres from the component to be coated. An Independent claim is also included for electropolishing components comprises applying cathode spheres to a flexible wire used as the cathode. The spheres are made of a material having a high specific electrical resistance which guarantees a predetermined distance of the cathode and/or cathode spheres from the component to be coated. Preferred Features: The anode/cathode moves during the coating or polishing process and touches the component to be processed. In the coating process, an adhesive layer containing nickel is applied followed by a second coating layer made of other materials.
