摘要： 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.

摘要： A hard drive disk substrate is formed of a multi-phase ceramic-based material having at least two phases with amorphous phases being present in an amount less than about 1 volume percent based on the volume of the ceramic-based material or at least one phase being free metal. A process for producing the ceramic-based disk substrate is produced by forming a flat disk of a porous ceramic and then infiltrating the porous ceramic with a metal whereby a multi-phase ceramic-based computer hard drive disk is produced. Additionally, a step of passivating the porous ceramic by elevating it to a temperature of about 1300.degree. to about 1800.degree. C. before the infiltrating step may be performed, such that the surfaces are passivated and the reaction kinetics can be controlled during the infiltrating step. A preferred composite material is made of a multi-phase boron carbide composite material including grains having peaks with an average roughness value, Ra, of between about 1 to about 200 .ANG., the roughness value being formed in situ by causing a micro hardness gradient of between about 19 and about 3200 Kg/mm.sup.2 in the various phases of the multi-phase boron carbide composite material.
