Gaswechselventil
Die Erfindung betrifft ein Gaswechselventil (1) einer Brennkraftmaschine, mit einem Ventilteller (2) und einem Ventilschaft (3). Erfindungswesentlich ist dabei, dass zumindest am Ventilschaft (3) zumindest bereichsweise eine galvanisch aufgebrachte Nickel-Phosphor-Schicht (4) aufweist, deren Phospho...

| description | Die Erfindung betrifft ein Gaswechselventil (1) einer Brennkraftmaschine, mit einem Ventilteller (2) und einem Ventilschaft (3). Erfindungswesentlich ist dabei, dass zumindest am Ventilschaft (3) zumindest bereichsweise eine galvanisch aufgebrachte Nickel-Phosphor-Schicht (4) aufweist, deren Phosphoranteil größer als 10 Vol.-% ist, insbesondere zwischen 11 und 13 Vol.-% liegt. Hierdurch kann die Verschleiß- und Korrosionsbeständigkeit verbessert werden.
A gas exchange valve of an internal combustion engine may include a valve plate and a valve stem. A nickel-phosphorus layer may be disposed on at least the valve stem. The nickel-phosphorus layer may have a phosphorus content that is greater than 10 percent by volume. A method and apparatus for coating a gas exhaust valve are also disclosed. |
