Abstract: A metal composite material is obtained by casting a melt of a metal and has an outer surface on which aluminum borate particles maintained in a porous form are exposed. Therefore, an oil is allowed to infiltrate the aluminum borate particles on the outer surface, to be retained therein and to ooze out during sliding. As a consequence, the sliding life during which desired sliding properties are maintained can be significantly prolonged. The metal composite material may be produced from a preform obtained by sintering aluminum borate particles covered with electrically neutralized silica and alumina particles which have been formed by mixing a silica sol and an alumina sol with aluminum borate particles in an aqueous solution to cover aluminum borate particles.

Abstract: A method through which we can synthesize Functionally Graded Materials (FGM). Such materials are made so that their composition changes gradually from one point to another, such as in the example of gradient index (GRIN) optical components. A novel aspect of our method is the imposition of a centrifugal force during the combustion synthesis of composite materials for structural, optical, or electronic applications, with the result that the composition and the particle size of the metallic (or ceramic) component changes continuously and across the thickness of the product. We have prepared such FGM as ZrO.sub.2 +Ni, ZrO.sub.2 +Cu and Al.sub.2 O.sub.3 +Cu.

Abstract: A technique for smoothing and otherwise changing the surfaces of porous bodies, such as ceramic molds, made using layer manufacturing processes, such as three dimensional printing processes. The surface finish of the mold can be smoothed by casting a slip of fine particles onto the surface to form a generally level, and preferably non-conformal, coating on the surfaces. In general, the fine particles of the slip are caused to be filtered out from the liquid, so that the fine particles come to rest at or near the surface of the body formed. They are typically, preferentially drawn toward concave regions of the surface, as compared to convex regions, thereby forming a non-conformal coating. Furthermore, other surface properties can be changed by tailoring the slip to produce those properties. The coating can be applied to external surfaces, and internal surfaces, such as would become the surface against which a molded part would be formed.

Abstract: A technique for removing loose powder from the interior surfaces of ceramic molds made using layer manufacturing processes, such as three dimensional printing processes. The interior of a mold is filled with water which is boiled and the particles are entrained in the flow caused by the boiling liquid. In another technique, the mold is immersed in water charged with CO.sub.2 and the pressure rapidly dropped to cause the CO.sub.2 to come out of solution as bubbles which eject the particles. Alternatively, fine particles are introduced into the mold and the mold is agitated to dislodge the particles and the powder so that they can be poured out of the mold. Such technique tends also to remove the surface finish of the mold. Any of the particles which remain can be dissolved in a liquid and removed in the liquid from the mold. Further, the surface finish of the mold can be improved by casting a slip of fine particles on to the surface to form a generally level, and preferably non-conformal, coating on the surfaces.

Abstract: Methods are known for producing a body from a material susceptible to thermal cracking, in particular from an alloy, by casting a melt of the material in a mold with thermally insulated side walls and a bottom of material with good thermal conducting properties and cooling the melt in the casting mold, where the solid-liquid interface forming as the border between the melt and the already solidified material essentially extends parallel to the bottom and, in the course of the solidification of the melt, moves from the bottom in the direction of the exposed surface of the melt. In order to provide a simple and cost-effective method, for producing plate-shaped bodies of material susceptible to thermal cracking, which permits the casting of crack-free and homogeneous bodies, the melt is poured into a casting mold, the temperature of which in degrees Celsius corresponds maximally to a third of the liquidus temperature of the material and is cast in the shape of a rectangular plate with a plate thickness in the range between 5 mm and 20 mm, where in the course of solidification of the melt, the solid-liquid interface moves essentially in the direction of one of the long sides of the plate.
