摘要： The performance and durability of static and dynamic seals for hydrogen storage and supply systems has been improved by utilizing a spring-energized and plastic coated radial seal in combination with at least a mating surface that has been treated by one of a variety of procedures. These procedures include applying to the mating surface a low-friction, hard, and hydrogen impervious coating, chemically polishing the mating surface, and electrochemically polishing the mating surface. Each of these procedures significantly reduces, on a microscopic scale, the surface roughness of the mating surface. The seal can thus form a tighter and more gas-tight seal with the smoother mating surface so as to decrease the loss of hydrogen gas across the seal. The smoother mating surface can also improve seal life by reducing seal surface wear.
摘要翻译： 通过利用弹簧通电和塑料涂覆的径向密封与至少已经通过各种程序之一处理的配合表面组合来改善氢储存和供应系统的静态和动态密封件的性能和耐久性。 这些方法包括向配合表面施加低摩擦，硬和不透氢的涂层，化学抛光配合表面，以及电化学抛光配合表面。 这些过程中的每一个在微观尺度上显着地减少配合表面的表面粗糙度。 因此，密封件可以与更平滑的配合表面形成更紧密和更气密的密封，以减少穿过密封件的氢气的损失。 更平滑的配合表面还可以通过减少密封表面磨损来提高密封寿命。

摘要： Hydrogen gas flow from high pressure storage to a lower pressure hydrogen-using device is managed using one or more axial flow pressure regulators comprising a cup-shaped housing with an inlet for high pressure hydrogen gas at one end of the flow axis and a closure with a low pressure hydrogen outlet at the other end of the flow axis. A piston head with a piston stem are aligned on the flow axis and a hydrogen flow passage is formed up the stem and through the piston head to the hydrogen flow outlet. One or more combinations of a corrugated tubular bellows (or like expansive sealing vessel) with static seals attaching one bellows end to the piston stem or head and the other bellows end to the housing or closure are used to accommodate axial movement of the piston while isolating and containing hydrogen gas flow from a high pressure chamber at a flow entrance to the piston stem to a low hydrogen pressure chamber at the piston head and closure outlet.

摘要： A method of creating adherent surface coatings on carbide cutting tools or other workpiece substrates through the development of polycrystalline diamond coatings or composite coatings comprising a refractory metal carbide and polycrystalline diamond is described. The coating is deposited through a sequenced chemical vapor deposition process, first using a specified gas mixture of hydrogen and a refractory metal halide to deposit a base layer of a refractory metal carbide. This step is followed by a second step in which polycrystalline diamond is deposited from a gas mixture comprising a hydrocarbon and hydrogen. Co-deposition of refractory metal carbide and diamond in the second step to create a toughened diamond coating is also contemplated.

摘要： A cutting tool for machining metal workpieces using polycrystalline diamond cutting surfaces with interspersed guide surfaces and chip evacuation surfaces. When machining holes in cast aluminum alloy workpieces it is found that aluminum machining chips adhere to guide surfaces and chip evacuation surfaces and mar the machined surface. It is found that when the guide and chip evacuation surfaces are coated with a diamond-like carbon material, aluminum chips do not mar the machined surfaces.

摘要： An intercalation electrode includes an electron current collector and graphene planes deposited normal to the surface of the current collector substrate. The graphene planes are deposited on the current collector substrate from a carbon-precursor gas using, for example, chemical vapor deposition. In an embodiment of an anode for a lithium-ion battery, the graphene planes are intercalated with lithium atoms. A lithium-ion battery may include this anode, a cathode, and a non-aqueous electrolyte. In repeated charging and discharging of the anode, lithium atoms and ions are readily transported between the graphene planes of the anode and the electrolyte.

摘要： A layered coating is disclosed herein. The layered coating includes a chromium layer, an intermediate layer of chromium and nitrogen established on the chromium layer, and an outer layer of chromium and nitrogen established on the intermediate layer. The intermediate layer has a gradually changing composition, wherein the chromium concentration decreases from an area of the intermediate layer adjacent the chromium layer towards a surface of the layered coating.
