Granted: 2000-10-11
Abstract: A method, and the structure formed thereby, of coating a fluidizable material onto a surface of a substrate wherein the substrate is not wettable by the fluidizable material includes depositing a layer of powder particles on the surface of the substrate, the powder particles being wettable by the fluidizable material; contacting the fluidizable material to the layer of powder particles; and allowing the fluidizable material to wick between the powder particles and to contact the surface of the substrate. Another aspect is a method for making a ceramic-metal tape which includes depositing a layer of a non-wettable ceramic powder onto a solid form; depositing a layer of a wettable powder onto the layer of the non-wettable ceramic powder; contacting a metal to the layer of the wettable powder; heating the metal to a temperature in which the metal melts and wicks through the layer of the wettable powder, and cooling the metal-infiltrated structure to solidify the metal. Another aspect is a method for bonding ceramic bodies together and the layered structure formed therefrom. The method includes coating a surface of a first ceramic body with non-reactive powder particles and reactive powder particles; abutting a surface of a second ceramic body against the coated surface of the first ceramic body; contacting the coating between the first ceramic body and the second ceramic body with a metal; and heating the metal so that the metal infiltrates through the powder particles.
