A METHOD OF REPAIRING A COMPONENT

摘要

AbstractA METHOD OF REPAIRING A COMPONENTThe present disclosure relates to a method of repairing a component (10).The method may comprise: removing a damaged portion (12) of the component to expose a region of the component; providing a patch (20) having a rim (22) exceeding the dimensions of the exposed region; placing the patch on the exposed region of the component such that the exposed region is covered by thepatch and the rim is spaced apart from the exposed region; joining the patch to the component around the rim of the patch; and diffusion bonding the patch and the component together. The rim (22) may be spaced apart from the exposed region such that the step of joining the patch (20) to the component (10) does not affect the exposed region. The method may further comprise machining arecess (14) in the damaged region of the component. The recess (14) may be covered by the patch (20). The recess (14) may be at least partially filled with a portion (20') of the patch. A replacement feature of the component may be provided on a surface of the patch.[Fig 1(d)]
