  • Method for plasma coating an object of elastomeric material
    Patent number: 8017196
    Abstract: A pump piston and/or elements sealing the pump piston, in particular a sealing ring of elastomeric material with an additionally applied coating are/is proposed. To improve the durability characteristics, the pump piston and/or the elements sealing the pump piston have a coating which is formed at least predominantly of halogen-, silicon-, carbon-containing and/or metal-organic monomers. Furthermore, a device and a method for coating an object of elastomeric material utilizing a plasma are proposed.
    Type: Grant

  • Method and device for coating at least one wiper-blade element
    Patent number: 6793978
    Abstract: The invention is based on a method for coating at least one wiper blade element (10) made of an elastomer material, in which first, the surface of the wiper blade element (10) is cleaned and activated by means of a plasma, and then in a CVD process, a coating material is brought into a plasma state and at least one protective coating (64) forms on the surface of the wiper blade element (10), where a high-frequency voltage is applied to the region of the wiper blade element (10) oriented away from the protective layer (64) by means of an electrode (56). The invention proposes that before being brought into a treatment chamber (32, 34, 36, 38, 40, 74), the wiper blade element (10) be cut to a useful length (66) from a profiled band and placed on an electrode plate (56) so that its wiper lip (18) stands approximately perpendicular to the electrode plate (56), which extends to both sides of the wiper blade element (10), and is subjected to a plasma flow (50).
