Abstract (en)
[origin: EP2439307A1] The method of coating a fuel injection component (1, 2), comprises forming the coating after manufacture of the component on a surface of the component, where the coating is formed as an oxide layer (11, 13) and acts as an anti-stick coating against aging and/or deposition components of the fuel. The formation of the oxide layer is carried out at the component by exposing the component at an elevated temperature of greater than 50[deg] C in an oxygen-containing atmosphere. A water vapor is exposed during or after formation of the oxide layer. The method of coating a fuel injection component (1, 2), comprises forming the coating after manufacture of the component on a surface of the component, where the coating is formed as an oxide layer (11, 13) and acts as an anti-stick coating against aging and/or deposition components of the fuel. The formation of the oxide layer is carried out at the component by exposing the component at an elevated temperature of greater than 50[deg] C in an oxygen-containing atmosphere. A water vapor is exposed during or after formation of the oxide layer. A chromium-containing steel (100Cr6) is used as a material for the component. The oxide layer is formed in form of a grind after a cutting surface treatment of the component. An independent claim is included for an arrangement.
