摘要： A process for manufacturing a boride dispersion copper alloy by preparing a metallic material having a surface portion comprising at least one of beryllium, gallium, manganese, nickel, palladium, silicon and vanadium, and copper or an alloy thereof, and diffusing boron into the surface portion. The resulting material includes fine boride particles uniformly dispersed in the surface portion and is useful as a material for electrical contacts or sliding parts due to its high resistance to adhesion, wear and arc, and excellent electrical conductivity and sliding properties.

摘要： The extreme pressure properties of ferrous metals can be increased by coating the metal with iron sulfide or chloride or mixtures thereof then heat treating the coated metal at a temperature in the range of 900*-2,000* F. for 1/2 to 24 hours. When metal Falex pins and jaws are treated in the above fashion they have longer running times, i.e., up to 11 times, than untreated pins and jaws under the same conditions in a standard Falex testing apparatus.

摘要： Aspects treat and remove a layer of scale comprising iron oxide and alloying elements oxides that is formed on an advanced high strength metal surface comprising at least two (2) percent by weight of alloy. A first conditioning process compromises structural integrity of or removes iron oxide within the scale layer to expose the alloy oxide to chemical engagement with a disposed aqueous alkali salt solution that is heated to transforming one or more alkali salts within the disposed solution into a quasi-molten form. The alloy oxide is oxidized via reaction with the solution quasi molten alkali salt(s) and water, forming one or more water soluble alkali alloy compounds. A water rinse dissolves and rinses the water soluble compound(s) from the steel product surface of the advanced high strength, leaving a film of iron oxide on the surface that is removed via a final pickling process.

摘要： In an aluminium-based coating for steel sheets or steel strips, the coating includes an aluminium-based coat applied in a hot-dip coating method, a covering layer containing aluminium oxide and/or hydroxide being arranged on the coat. The covering layer is produced by plasma oxidation and/or hot water treatment at temperatures of at least 90° C., advantageously at least 95° C., and/or steam treatment at temperatures of at least 90° C., advantageously at least 95° C. Alternatively, the covering layer containing aluminium oxide and/or hydroxide can be produced by anodic oxidation, the coat being produced in a molten bath with a Si content of between 8 and 12 wt. %, and an Fe content of between 1 and 4 wt. %, the remainder being aluminium.

摘要： A framework of copper oxide dendrites is formed on a copper substrate, and these are then coated or plated with silver, gold, or an equivalent metal to create metal-coated dendrites with nano-structures, favorably in range of 50 to 200 nanometers. The framework of metal-coated dendrites are well suited for use in surface-enhanced Raman spectroscopy and other practical applications.

摘要： A treatment process for a gas turbine component comprising a bond coating and a ceramic coating, an oxide-forming treatment composition, and a treated component are disclosed. The ceramic coating is contacted with a treatment composition. The treatment composition includes a carrier and a particulate oxide-forming material suspended within the carrier. The particulate oxide-forming material is one or more of yttria oxide, antimony, or tin oxide. The treatment composition is heated to form an oxide overlay coating on the ceramic coating. The treated component includes a ceramic coating and one or both of a corrosion inhibitor and an oxide formed by an oxide-forming treatment composition having the corrosion inhibitor.

摘要： The present invention provides a blackening treatment method for a black Cr—Co alloy plating film, the method comprising bringing a black Cr—Co alloy plating film having a Cr content of 1 to 15 wt. % into contact with a blackening treatment solution comprising an aqueous solution with a pH value of −1 to 5. According to the present invention, the blackish color of a less blackish plating film formed from a plating bath containing trivalent chromium is enhanced to further improve decorativeness. Furthermore, the corrosion resistance of the film can be more improved by performing electrolytic chromate treatment after blackening treatment.

摘要： A method for finely powdering tungsten powder, which includes: a process for classifying a material tungsten powder into a fine powder having a relatively small average particle diameter and a coarse powder having a relatively large average particle diameter; an oxidation process for forming an oxide film on the particle surface of the coarse powder; and an alkali treatment process for removing the oxide film formed in the oxidation process and a natural oxide film formed on the fine powder with an alkali aqueous solution. Also disclosed is a method for producing ultrafine tungsten powder, which includes obtaining tungsten powder having an average particle diameter of 0.04 to 0.4 μm and a BET specific surface area of 5 to 15 m2/g by the above method for finely powdering.
