Abstract: A process for making a porous mass of a metal of iron- or titanium-group comprises steps of forming a sinter of solvent-soluble particles, pressing in a molten metal of the iron- or titanium- group into open interstices in the sinter, and eluting the particles from the composite of the sinter and metal. Solvent-soluble magnesia particles whose surface is either covered or not with a film of boric anhydride or solvent-soluble calcia particles whose surface is either covered or not with film of calcium chloride are sintered and machined into the desired shape. The formed sinter is put in a case of a heat-insulating material that can withstand the melting temperature of a metal of iron- or titanium-group. After being heated to a given temperature together with the case, the sinter is immediately put in a metal mold where a molten metal of iron- or titanium-group is pressed into open interstices in the sinter. Then, only the particles are eluted from the sinter-metal composite by a solvent.

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: This invention relates generally to a novel method of preparing self-supporting bodies and to the novel products made thereby. In its more specific aspects, this invention relates to a method of producing self-supporting bodies having controlled porosity and graded properties and comprising one or more boron-containing compounds, e.g., a boride or a boride and a carbide. The method comprises, in one embodiment, reacting a powdered parent metal, in molten form, with a bed or mass comprising a boron carbide material and, optionally, one or more inert fillers, to form the body. In another embodiment, both of a powdered parent metal and a body or pool of molten parent metal are induced to react with a bed or mass comprising a boron carbide material and, optionally, one or more inert fillers. in addition, combustible additives (e.g., gelatin, corn starch, wax, etc.) can be mixed with the bed or mass comprising a boron carbide material to aid in the porisity producing process. When the self-supporting body of the instant invention is formed while in contact with a previously formed ceramic, metal or composite body, a bond can be formed between the two bodies, thus creating a macrocomposite body.
