Abstract

Die Erfindung betrifft ein Einspritzventil (1) für eine Brennkraftmaschine. Das Einspritzventil (1) umfasst einen Ventilkörper (5) mit einem Ventilkopf (6), wobei der Ventilkopf (6) dazu ausgebildet ist, um zumindest abschnittsweise in einem Brennraum (4) der Brennkraftmaschine angeordnet oder diesem zumindest unmittelbar zugewandt zu sein. Weiterhin ist der Ventilkopf (6) wenigstens bereichsweise mit einer ersten Oxid-Schicht (9) beschichtet. Erfindungsgemäß ist über der ersten Oxid-Schicht (9) eine zweite Oxid-Schicht (10) aus Ceroxid (CeO2) und/oder Praseodymoxid (PrO2) und/oder Zirconiumoxid (ZrO2) angeordnet. Weiterhin wird ein Verfahren zur Herstellung eines solchen Einspritzventils (1) aufgezeigt. Erfindungsgemäß wird hierzu die über der ersten Oxid-Schicht (9) anzuordnende zweite Oxid-Schicht (10) aus Ceroxid (CeO2) und/oder Praseodymoxid (PrO2) und/oder Zirconiumoxid (ZrO2) als Washcoat aufgebracht.

The invention relates to an injection valve (1) for an internal combustion engine. The injection valve (1) comprises a valve body (5) with a valve head (6), wherein the valve head (6) is designed to be at least partially disposed in a combustion chamber (4) of the internal combustion engine or at least directly facing it. Furthermore, the valve head (6) is at least partially coated with a first oxide layer (9). According to the invention, a second oxide layer (10) of cerium oxide (CeO 2 ) and / or praseodymium oxide (PrO 2 ) and / or zirconium oxide (ZrO 2 ) is arranged above the first oxide layer (9). Furthermore, a method for producing such an injection valve (1) is shown. According to the invention, the second oxide layer (10) of cerium oxide (CeO 2 ) and / or praseodymium oxide (PrO 2 ) and / or zirconium oxide (ZrO 2 ) to be arranged above the first oxide layer (9) is applied as a washcoat for this purpose.
