METHOD FOR FORMING A COMPOSITE ARTICLE

摘要

A method for forming a composite article includes providing a metallic substrate and a preform adjacent the metallic substrate. The preform includes an unfused metallic powder material with an organic binder dispersed through the powder material. The metallic substrate and the preform are then subjected to a monocyclic heating process. The monocyclic heating process causes removal of the organic binder from the preform, fusing of the metallic powder material and metallurgical bonding of the metallic powder to the metallic substrate.
