  • Patent number: 9217296
    Abstract: Polycrystalline ultra-hard constructions comprise a polycrystalline ultra-hard material body and two or more support members attached to the body by braze material. The support members include a backside support member and a side support member. The side support member is a one- or two-piece construction, and is positioned circumferentially around and extends axially along the body or both the body and the backside support member such that a working surface of the body remains exposed. The support members can be configured to provide a mechanical attachment or interlocking attachment with the body or another support member. The braze materials used in the construction can be different and selected to enhance the attachment and/or reduce the creation of thermal stress within the construction during assembly. The support members can be selected having different thermal expansion characteristics that also operate to reduce the thermal stress during construction assembly.

  • Patent number: 9178223
    Abstract: A fuel cell separator 60 having a metal plate and an anticorrosion resin coating layer 55 formed thereon is provided, with which adhesion between the resin coating layer 55 and its counterpart member is further increased and the durability of a fuel cell unit is improved. In forming the fuel cell separator 60 having a separator substrate 50 that is a metal plate and an anticorrosion resin coating layer 55 formed thereon, the resin coating layer 55 is formed such that it has a surface roughness Ra of 0.5 to 13.5 ?m. Increasing the surface roughness will produce an anchoring effect, which will improve the adhesive force at the interface. The aforementioned surface roughness Ra can be obtained either with the use of fillers that are mixed into the resin coating layer 55 or with external force applied to the surface of the resin coating layer 55 by means of shot blasting, for example.

  • Patent number: 9150968
    Abstract: High-surface-area carbon nanostructures coated with a smooth and conformal submonolayer-to-multilayer thin metal films and their method of manufacture are described. The manufacturing process may involve initial oxidation of the carbon nanostructures followed by immersion in a solution with the desired pH to create negative surface dipoles. The nanostructures are subsequently immersed in an alkaline solution containing non-noble metal ions which adsorb at surface reaction sites. The metal ions are then reduced via chemical or electrical means and the nanostructures are exposed to a solution containing a salt of one or more noble metals which replace adsorbed non-noble surface metal atoms by galvanic displacement. Subsequent film growth may be performed via the initial quasi-underpotential deposition of a non-noble metal followed by immersion in a solution comprising a more noble metal.
