A method for forming a vehicular brake rotor involving loading a shaped metal substrate with a mixture of metal alloying components and ceramic particles in a dieheating the contents of the die while applying pressure to melt at least one of the metal components of the alloying mixture whereby to densify the contents of the die and form a ceramic particle-containing metal matrix composite coating on the metallic substrate; and cooling the resulting coated product.

Systems and methods for forming a layer onto a surface of a solid substrate and products formed thereby

A system for purification of high value metals comprises an electrolytic cell in which an anode formed of a composite of a metal oxide of the metal of interest with carbon is electrochemically reduced in a molten salt electrolyte.

Thermal and electrochemical process for metal production

A method for producing a pure metal M or metal alloy MN, of interest, which comprises electrolyzing a molten salt electrolyte of an alkali-metal or alkaline-earth metal halide AX or AX, with an anode formed of graphite or made of a composite of a metal oxide of the metal of interest and carbon, to discharge the alkali or alkaline-earth metal A, at the cathode, and to discharge nascent chlorine gas at the anode, whereby to produce a halide of the metal of interest MXand/or NX, and metallothermically reducing the metal halide MXand/or NXeither separately or combined, with the alkali or alkaline-earth metal A, obtained cathodically to produce the metal M or the metal alloy MNof interest in particulate form.

Metallothermic reduction of in-situ generated titanium chloride

Low cost spherical titanium and titanium powder alloy powder is produced by impinging a stream of an inert gas, such as argon, on the surface of a molten pool of titanium or sponge and alloying elements.

Low cost processing to produce spherical titanium and titanium alloy powder

Discontinuous diamond particulate containing metal matrix composites of high thermal conductivity and methods for producing these composites are provided. The manufacturing method includes producing a thin reaction formed and diffusion bonded functionally graded interactive SiC surface layer on diamond particles. The interactive surface converted SiC coated diamond particles are then disposed into a mold and between the particles and permitted to rapidly solidify under pressure. The surface conversion interactive SiC coating on the diamond particles achieves minimal interface thermal resistance with the metal matrix which translates into good mechanical strength and stiffness of the composites and facilitates near theoretical thermal conductivity levels to be attained in the composite. Secondary working of the diamond metal composite can be performed for producing thin sheet product.

High thermal conductivity metal matrix composites

A penetrator comprising a layered composite of at least one high density metal and at least one reactive metal material such as a reactive metal.

Multi component reactive metal penetrators, and their method of manufacture

A process for manufacturing Ti alloy structures using a SFFF manufacturing process with a welding torch as a high energy source, which comprises using as a feed a feed wire made from Ti sponge and alloying powders, or forming a Ti alloy in-situ in the melt.

Low cost process for the manufacture of near net shape titanium bodies

A method of material treatment in which the surface of a metal substrate is converted to a composite structure of the metal and its nitride or carbide utilizing a high temperature chemically active thermal plasma stream, and the product obtained from that method. The complex thermal plasma contains controllable additions of active gas, liquid or solid substances. The surface layer obtained is functionally graded to the substrate resulting in an excellent bond that resists delamination and spalling, and provides a significant increase in hardness, wear and erosion resistance, and corrosion resistance, and a decrease in coefficient of friction.
