摘要： A process and apparatus for forming wires, such as wires used as feedstock in welding, brazing, and coating deposition processes. The process and apparatus generally entail feeding through a passage a quantity of powder particles of a size and composition that render the particles susceptible to microwave radiation. As the particles travel through the passage, the particles within the passage are subjected to microwave radiation so that the particles couple with the microwave radiation and are sufficiently heated to melt at least a radially outermost quantity of particles within the passage. The particles are then cooled so that the radially outermost quantity of particles solidifies to yield a wire having a consolidated outermost region surrounding an interior region of the wire.

摘要： A braze material and processes for making and using the material, such as for use in the manufacturing, coating, repair, and build-up of superalloy components. The braze material is composed of particles with melt-modifying constituents that are limited to the surfaces of the particles, yet are capable of sufficiently promoting the heating of the particles by conventional means and microwave radiation to achieve at least partial melting of the particles. The melt-modifying constituents are in the form of particulates embedded in the outer surface region of each particle. The particulates are formed of melting point depressant(s) and/or microwave coupling enhancer(s), are much smaller than the particle in which they are embedded.

摘要： A nickel-based high-temperature braze alloy composition includes Cr, Hf, and B. Furthermore, a cobalt-based high-temperature braze alloy composition includes Cr, Hf, and B. The braze alloys can be used, for example, as a single homogenous braze.

The braze alloys may permit joining/repairing of superalloy articles with complex shape and may be used in high temperature applications.

摘要： A process for forming a coating on a surface of a substrate, so that heating of the coating material is selective and sufficient to cause at least partial melting of the coating material and permit bonding to the substrate without excessively heating the substrate so as not to significantly degrade its properties. The process generally entails forming a brazing paste containing powder particles dispersed in a binder. The particles are formed of a composition that is susceptible to microwave radiation. The brazing paste is then applied to the surface of the substrate and subjected to microwave radiation so that the particles couple with the microwave radiation and are sufficiently heated to burn off the binder and then at least partially melt to form an at least partially molten layer on the substrate. The microwave radiation is then interrupted to allow the at least partially molten layer to cool, solidify, and form the coating.
