Patent ID: 7981331

Claim:
A method for repairing a wear-induced void on a surface of a cavity of a component using an expandable bladder, the bladder being coupled to a frame that is configured to be inserted into the cavity, the frame being configured to restrain the expansion of the bladder so as to directionally expand the bladder, the method comprising: applying a heat-cured ceramic material to the wear-induced void, wherein the heat-cured ceramic material is configured to substantially fill the wear-induced void; inserting the frame into the cavity and aligning the frame opposite the wear-induced void; providing a volume of material to the bladder to expand the bladder against the frame so as to isolate the expansion of the bladder against the cavity in only the vicinity of the wear-induced void; and applying at least one of pressure and heat, via the bladder, to cure the heat-cured ceramic material.
