Manufacture of near-net shape titanium alloy articles from metal powders by sintering with presence of atomic hydrogen

The present invention relates to design and manufacture of multilayer sintered membranes made from metals and inorganic compounds (ceramics, silicate, clay, zeolites, phosphates, etc.). The membranes are designated for separation of water. They comprise at least one layer having nanopores commensurable with the size of water molecules. The membranes comprise: (a) supporting metallic layer having pore size 1-500 microns, (b) metallic interlayer having pore size &#x3c;2 micron, (c) sublayer with local regular protrusions of the interlayer into the supporting layer to increase service life of the membrane, and (d) one nanoporous ceramic or metallic top layer having pore size in the range of 1-15 angstroms. The invented design and method allow the manufacture of cost-effective multilayer membranes containing nanoporous layer with controlled pore sizes in each layer and optimal morphology of pores that provides selective transport of molecules during filtration and separation of liquids.

Multilayer, micro- and nanoporous membranes with controlled pore sizes for water separation and method of manufacturing thereof

The invention relates to energy-saving manufacturing of purified hydrogenated titanium powders or alloying titanium hydride powders, by metallo-thermic reduction of titanium chlorides, including their hydrogenation, vacuum separation of titanium hydride sponge block from magnesium and magnesium chlorides, followed by crushing, grinding, and sintering of said block without need for any hydro-metallurgical treatment of the produced powders. Methods disclosed contain embodiments of processes for manufacturing high purity high-purity powders and their use in manufacturing near-net shape titanium and titanium-alloy articles by sintering titanium hydride and alloyed titanium hydride powders produced from combined hydrogen-magnesium reduction of titanium chlorides, halides and hydrides of other metals. Additional titanium hydride powder introduced with titanium tetrachloride beneficially affects the kinetics of magnesium-thermic reduction due to formation of additionally-emitted atomic hydrogen, which helps to reduce presence of oxides, and so cleans inter-particle interfaces of the product and enhances diffusion between all components of the powder mixture.
