Abstract: A substrate is coated by applying a first layer atop the substrate and comprising, in major weight part, a non-refractory first metal. A second layer is applied atop the first layer and comprises, in major weight part, a carbide and/or nitride of a second metal. A third layer is applied atop the second layer and comprises, in major weight part, a ceramic. The substrate may be a refractory metal-based investment casting core.

Abstract: An at least two step heating process is used to strengthen the shell of an investment casting mold including a refractory metal core. The first stage (46) may occur under otherwise oxidizing conditions at a low enough temperature to avoid substantial core oxidation. The second stage (56) may occur under essentially non-oxidizing conditions at a higher temperature.

Abstract: A substrate is coated by applying an essentially pure aluminum first layer to a surface of the substrate. At least a first portion of the first layer is oxidized so as to provide a protective coating of desired properties. The substrate may be a refractory metal-based investment casting core.

Abstract: A method for forming or remanufacturing a component (22) to have an internal space. A refractory metal blocking element (100; 152, 154) is positioned with at least a portion (104; 156) to be within the internal space. A material is added by at least one of laser cladding and diffusion brazing, the blocking element (100; 152, 154) at least partially blocking entry of the material to the internal space. The blocking element (100; 152, 154) is removed.

Abstract: Se reduce un sustrato al aplicar una primera capa de aluminio esencialmente puro a una superficie del sustrato. Por lo menos una primera porcion de la primera capa se oxida de manera que proporciona un recubrimiento protector de propiedades deseadas. El sustrato puede ser un nucleo de fundicion a la cera perdida basado en metal refractario.
