| description | The invention relates to an engine valve comprising a chromiferous steel and a protective surface layer (5) which consists of iron chrome oxide. The invention relates further to a method for manufacture of an engine valve with a protective layer characterised in that: -an engine component comprising a chromiferous steel is provided (100); -the engine component is heated (200) at a predetermined temperature for a predetermined time so that a layer (5) of iron chrome oxide is formed on the engine component's surface; -the engine component is cooled (300) to room temperature.
L'invention concerne une soupape de moteur comprenant un acier chromifère et une couche protectrice de surface (5) qui contient un oxyde de chrome-fer. L'invention concerne également un procédé de fabrication de soupape de moteur à couche protectrice caractérisé en ce que : - un composant de moteur comprenant un acier chromifère est utilisé (100) ; - le composant de moteur est chauffé (200) à une température prédéterminée pendant une durée prédéterminée de telle sorte qu'une couche d'oxyde de chrome-fer (5) est formée sur la surface du composant de moteur ; - puis le composant de moteur est refroidi (300) à température ambiante. |
