METHOD OF REPAIRING A COMPONENT

摘要

A method of repairing a component comprising: removing a damaged portion of the component to expose a region of the component; providing a patch having a rim 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 the patch 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 may be spaced apart from the exposed region such that the step of joining the patch to the component does not affect the exposed region. The method may further comprise machining a recess in the damaged region of the component.
