SUPERFINE/NANOSTRUCTURED CORED WIRES FOR THERMAL SPRAY APPLICATIONS AND METHODS OF MAKING

摘要

Cored wires having a core comprising agglomerates of superfine particles and/or nanoparticles for thermal spray or overlay weld applications and methods of making the same are provided. Methods of coating a substrate by thermal spraying such as electric arc spraying with such cored wires are also provided. In an embodiment, a cored wire comprises a metallic sheath at least partially surrounding a core comprising agglomerates of superfine particles, nanoparticles, or a combination comprising at least one of the foregoing particles.
