Process for the repair of DLC-coated components and DLC-coated aircraft components

摘要

The invention relates to a method for repairing components (1) coated with DLC as well as an aircraft component (1) coated with DLC. The method comprises the steps: evaporation and / or conversion of the DLC layer (8) by irradiation with a laser, wherein the properties of the laser radiation and the irradiation parameters are selected so that the carrier material underneath the DLC layer (8) is not impaired; and- cleaning the carrier material by blasting with a blasting agent which does not impair the carrier material.The aircraft component (1) is a variable guide vane provided for use in an aircraft engine, comprising an aerodynamically shaped vane area (2) with the vane surface (3) and an axis of rotation (4) , bearing journals (5) being provided coaxially with the axis of rotation (4) at both ends of the blade area for rotatable mounting in coaxially arranged bearing journal receivers, the bearing journals (5) each projecting from a stop surface (6) for contact with an end face of the bearing journal receivers are. The outer surfaces of the bearing journals (5) and the stop surfaces (6) are provided with a DLC layer (8) which can be repaired using a method according to the invention.
