Abstract
A clad article of a substrate of one powdered metal that is clad with a second dissimilar powdered metal. A separation layer may be provided between the substrate and the clad layer to separate these layers during consolidation and to facilitate bonding thereof. The consolidation operation may be performed by hot isostatic pressing of the powders within a deformable container.
Claims23
A clad article comprising, a substrate of one powdered metal, and a clad layer of a second dissimilar powdered metal bonded to said substrate to from said clad article.
A clad article comprising, a substrate of one powdered metal, and a clad layer of a second dissimilar powdered metal bonded to said substrate, with a solid metal separation layer between said substrate and said clad layer, to form said clad article.
A method of producing a clad article having a substrate of one powdered metal and a clad layer of a second dissimilar powdered metal bonded to said substrate to form said clad article, said method comprising:
- providing a deformable container;
- positioning within said deformable container a layer of powder of said one powdered metal and an adjacent layer of powder of said second dissimilar powdered metal;
- and
- deforming said container to consolidate and bond said layer of powder and said adjacent layer of powder to substantially full density to form said clad article.
