Exhaust gas line used for a vehicle operated with a diesel engine has a metallic guiding element coated with vanadium oxide

摘要

Exhaust gas line has a metallic guiding element coated with V2O5. An Independent claim is also included for a process for the production of an exhaust gas line comprises producing a metallic guiding element and coating the surface of the element with V2O5. Preferred Features: The coating is doped with platinum or lanthanum and/or cerium. The surface of the element is coated before being coated. A layer made from chromium oxide and/or manganese oxide is applied between the V2O5 coating and the surface of the element. The coating is applied using a galvanic bath.
