Abstract
A method 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. The method of the invention provides a method which requires little or no binders or organic solvents, is applicable to many different ceramic-metal formulations, allows easy control of the thickness of the tape, forms fairly dense tapes so that little or no shrinkage occurs upon densification at elevated temperatures, and does not require undesirably high processing temperatures.
