Abstract: 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.

Abstract: 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.
Abstract translation: 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。

Abstract: 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.
