Abstract
A method for repairing a component of a gas turbine engine is provided. The method includes perforating apertures through a braze tape based on a shape of a degraded region of the component, and applying the braze tape to the component such that the braze tape covers the degraded region and the apertures surround a perimeter of the degraded region. The method also includes bonding the braze tape and the component via a thermal brazing treatment, and contouring the braze tape to conform to an original profile of the component based on monitoring depths of the apertures.

A method for repairing a component of a gas turbine engine, the method comprising:
- perforating apertures through a braze tape based on a shape of a degraded region of the component;
- applying the braze tape to the component such that the braze tape covers the degraded region and the apertures surround a perimeter of the degraded region;
- bonding the braze tape and the component via a thermal brazing treatment;
- and
- contouring the braze tape to conform to an original profile of the component based on monitoring depths of the apertures.
A method for repairing a component of a gas turbine engine, the method comprising:
- perforating apertures through a braze tape based on a shape of a degraded region of the component;
- applying the braze tape to the component such that the braze tape covers the degraded region and the apertures overlie an undamaged surface of the component;
- bonding the braze tape and the component;
- grinding excess material from the braze tape based on an original profile of the component while monitoring depths of the apertures;
- and
- ceasing the grinding based on an increased exposure of the undamaged surface of the component at locations of the apertures.
A method for repairing a component of a gas turbine engine, the method comprising:
- perforating apertures through a braze tape based on a shape of a degraded region of the component;
- applying the braze tape to the component such that the braze tape covers the degraded region;
- applying a braze-resist coating to interior surfaces of the apertures;
- bonding the braze tape and the component via a thermal brazing treatment, wherein the braze-resist coating blocks migration of a braze alloy of the braze tape into the apertures;
- and
- contouring the braze tape to conform to an original profile of the component based on monitoring depths the apertures.
