Abstract: A method is disclosed for forming corrosion-resistant joints in a plurality of overlapping thin metal sheet workpieces, at least one of which comprises at least 85% by weight of magnesium sheets. The fastener is a fiber-reinforced polymer rod shaped and sized for insertion into a coaxial opening formed in each sheet and subsequently upset on each end to form a head. The workpiece sheets are deformed to form mechanically-interfering features which cooperatively complement the strength of the fastener, under at least some joint loading patterns. The method may be used for other workpiece and fastener compositions.

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: A method for connecting individual lithium ion cells into a battery suited for powering an electric or hybrid vehicle is disclosed. The cell current collectors are electron beam welded to one another and to a connector tab in an substantially oxygen-free atmosphere. The cell current collectors and the connector tab are temporarily secured with a clamp, one portion of which has an opening. The electron beam size may be controlled, by magnetic coils and by the extent of electron scattering by the gas atmosphere, to minimally fill the clamp opening to minimize any irradiation of the clamp. The beam or the workpieces may be displaced, if required, fuse the entire opening area. A similar procedure may be followed to weld a plurality of connector tabs to a busbar.

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.
