    摘要： 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. SiO2 & B2O3) 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. CH4), nitrogen containing (e.g. NH3), and boron-containing (e.g. B2H6) 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.

    摘要： A method of manufacturing a part is provided. The method includes heating a gear in the presence of carbon to carburize a material of the gear to create a carburized gear, the gear having a plurality of gear teeth and which comprises a selected material. Next, the carburized gear is high pressure gas quenched to drive the carbon into the material of the gear to create a quenched gear. Next, the quenched gear is at least one of cavitation peened and laser peened to create a peened gear. Finally, superfinishing is performed on surfaces of the peened gear.

    摘要： A method for manufacturing a carbon nanostructure according to an embodiment of the present invention is a method for manufacturing a carbon nanostructure, the method including a preparation step of preparing a substrate containing a carburizable metal as a main component, and a carbon nanostructure growth step of supplying a carbon-containing gas while heating the substrate, in which the carbon nanostructure growth step includes gradually cleaving a heated portion of the substrate. The cleaving in the carbon nanostructure growth step is preferably performed by subjecting the substrate to shearing. The heating in the carbon nanostructure growth step is preferably performed by irradiating a cleaving portion of the substrate with a laser. The preparation step preferably includes forming, in the substrate, a notch for inducing cleavage. Preferably, the substrate in the carbon nanostructure growth step is not oxidized.
