Abstract

Gassutvekslingsventil for en forbrenningsmotor med en ventilkjegle i det vesentlige fra en ventilstamme som ved utforming av en hulkil går over i en ventiltallerken, og ventilkjeglen eller i det minste ventilstammen frem til området ved hulkilen er fremstilt av et typisk ventilstål fra en nitriddannende basislegering, kjennetegnet ved at ventilkjeglen i det minste i delområder er forsynt med et korrosjonsbeskyttelsessjikt i form av et nitridsjikt hhv. karbonnitridsjikt, idet korrosjonsbeskyttelsessjiktet er tilveiebrakt ved omsetning av den nitriddannende basislegering ved plasmanitrering eller plasmanitrokarburering i en nitrogenatmosfære.Gas exchange valve for an internal combustion engine with a valve cone substantially from a valve stem which, when forming a hollow wedge, passes into a valve plate, and the valve cone or at least the valve stem to the region of the hollow wedge is made of a typical valve steel from a nitride-forming base alloy, that the valve cone is provided at least in sub-regions with a corrosion protection layer in the form of a nitride layer respectively. carbon nitride layer, the corrosion protection layer being provided by reaction of the nitride-forming base alloy by plasma nitration or plasma nitrocarburation in a nitrogen atmosphere.
