Abstract
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.
Claims18
A method for forming a composite article, the method comprising:
- providing an iron-based substrate having a first hardness;
- arranging adjacent a preform in contact with a surface of the iron-based substrate, the preform including an unfused metallic powder material with an organic binder dispersed there through;
- subjecting the iron-based substrate and the preform to a monocyclic heating process, the monocyclic heating process converting the preform into a wear-resistance element having a second, greater hardness and that is metallurgically bonded on the iron-based substrate;
- and
- wherein the metallic powder material is a nickel-based alloy.
