COMPOSITE MATERIALS AND METHODS FOR LASER MANUFACTURING AND REPAIR OF METALS

摘要

Composite materials (2, 8) disclosed herein include a metal alloy (4, 10) and a flux composition (6, 12). The metal alloy may be a superalloy, and a volume ratio of the flux composition to the metal alloy may range from about 30:70 to about 70:30. The composite materials may be in the form of particles (2) containing a core (6) surrounded by a metallic layer (4), in which the core contains the flux composition and the metallic layer contains the metal alloy. The composite materials may also be in the form of fused materials (8) in which the metal alloy (10) and the flux composition (12) are randomly distributed and randomly oriented. Also disclosed are processes involving melting of composite materials to form metal deposits (32).
