More Information
Summary:In one aspect, composite preforms for the repair of superalloy parts and/or apparatus are described herein. For example, a composite preform comprises a nickel-based superalloy powder component, a nickel-based braze alloy powder component and a melting point depressant component disposed in a fibrous polymeric matrix. The fibrous polymeric matrix can form a flexible cloth in which the nickel-based superalloy powder component, nickel-based braze alloy powder component and melting point depressant component are dispersed.
