Mechanically-assisted gaseous addition of hydrogen to metal alloys
An article formed of a metal alloy is covered at least partially with a metal hydride and a shell metal to form an assembly. Load is applied to the assembly and the assembly is heated. The shell metal deforms around the article and the metal hydride and forms a gas proof seal. The metal hydride thermally decomposes to form hydrogen gas. At least a portion of the hydrogen gas dissociates and moves as monoatomic hydrogen into the article. The metal alloy can be a zirconium metal alloy, the metal hydride can be a zirconium metal hydride, and the shell metal can be substantially copper.

Method for growing a transition metal dichalcogenide layer, transition metal dichalcogenide growth device, and method for forming a semiconductor device
A method for growing a transition metal dichalcogenide layer involves arranging a substrate having a first transition metal contained pad is arranged in a chemical vapor deposition chamber. A chalcogen contained precursor is arranged upstream of the substrate in the chemical vapor deposition chamber. The chemical vapor deposition chamber is heated for a period of time during which a transition metal dichalcogenides layer, containing transition metal from the first transition metal contained pad and chalcogen from the chalcogen contained precursor, is formed in an area adjacent to the first transition metal contained pad.
Method for manufacturing filled container, and filled container
The method for producing a filled container of the present invention includes: providing a metal storage container, at least an inner surface of which is formed of a manganese steel and in which the inner surface has a surface roughness R.sub.max of 10 μm or less; performing fluorination by bringing the inner surface of the storage container into contact with a gas containing at least one first fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6 at 50° C. or lower; purging the inside of the storage container with an inert gas; and filling the inside of the storage container with at least one second fluorine-containing gas selected from the group consisting of ClF.sub.3, IF.sub.7, BrF.sub.5, F.sub.2, and WF.sub.6.

ACTIVATION OF SELF-PASSIVATING METALS USING REAGENT COATINGS FOR LOW TEMPERATURE NITROCARBURIZATION IN THE PRESENCE OF OXYGEN-CONTAINING GAS
A method for low-temperature interstitial case formation on a self-passivating metal workpiece includes exposing the workpiece in a heated gaseous environment comprising oxygen to pyrolysis products of a nonpolymeric reagent comprising nitrogen and carbon.
METHOD FOR FORMING BINDER-FREE REFRACTORY CARBIDE, NITRIDE AND BORIDE COATINGS WITH A CONTROLLED POROSITY
The present invention is directed to methods for formation of refractory carbide, nitride, and boride coatings without use of a binding agent. The present invention is directed to methods of creating refractory coatings with controlled porosity. Refractory coatings can be formed from refractory metal, metal oxide, or metal/metal oxide composite refractory coating precursor of the 9 refractory metals encompassed by groups 4-6 and periods 4-6 of the periodic table; non-metallic elements (e.g. Si & B) and their oxides (i.e. SiO.sub.2 & B.sub.2O.sub.3) are also pertinent. The conversion of the refractory coating precursor to refractory carbide, nitride or boride is achieved via carburization, nitridization, or boridization in the presence of carbon-containing (e.g. CH.sub.4), nitrogen containing (e.g. NH.sub.3), and boron-containing (e.g. B.sub.2H.sub.6) gaseous species. Any known technique of applying the refractory coating precursor can be used. The porosity of resultant refractory coatings is controlled through compositional manipulation of composite refractory coating precursors.
