Pioneering corrosion protection by new plasma technology

A major supplier to the automotive sector has recently started using plasma technology for pretreating motor pump housings. With the new process the surfaces of metallic components are selectively coated in-line at atmospheric pressure to prevent bond line corrosion. Whether the aim is to provide protection against corrosion or to facilitate cleaning of a surface, the PlasmaPlus technology newly developed by Plasmatreat GmbH based in Steinhagen, Germany in collaboration with the Fraunhofer IFAM, Bremen, offers an abundance of different layers for selective coating. The basis of the new process is the Open-Air Atmospheric-Pressure Plasma technology that is already used throughout the world. A large supplier to the automotive sector has been using this technology since early in 2008 to protect steering system components against corrosion. More information...
