  • Patent number: 6803078
    Abstract: The invention relates to a process for producing a surface layer with embedded inter-metallic phases, which is distinguished by the fact that a layer comprising a metal and a ceramic is applied to a substrate element, that a reaction takes place between the metal and the ceramic of the layer as a result of energy being introduced during the application of the layer or as a result of a subsequent introduction of energy, and as a result the surface layer is produced, with inter-metallic phases being formed.

    Abstract: High areal storage density, patterned magnetic media comprising a patterned plurality of at least partially crystalline, ferromagnetic particles or grains are provided by means of a simple, economical process wherein a non-magnetic substrate is provided with a layer of an amorphous, paramagnetic or anti-paramagnetic material comprising at least one component, e.g., a metal element, which is ferromagnetic when in at least partially crystalline form, and at least partially crystallizing the at least one component at selected areas of the amorphous layer to form a spaced-apart pattern of at least partially crystallized, ferromagnetic particles or grains of the at least one component, the particles or grains being spaced apart and surrounded by a matrix of the amorphous material. Embodiments include utilizing a focussed or scanned laser source and an amorphous Ni—P layer for forming ferromagnetic Ni particles or grains.

  • Patent number: 6733875
    Abstract: A porous member for pneumatic bearings or the like provides a controlled gas flow rate across a porous ceramic body, which can be readily achieved by a facilitated treatment. The porous body has its outer surface portion covered by a surface layer comprised of fine silica particles which are impregnated in the porous body. The surface layer is subjected to a heat treatment to form restricted passages which are in communication with, and smaller in size than pores within the porous body.

  • Publication number: 20030198749
    Abstract: A complexly shaped Si/SiC cermet part including a protective coating deposited on a surface of the cermet part facing the plasma of the reactor. The cermet part is formed by casting a SiC green form and machining the shape into the green form. The green form is incompletely sintered such that it is unconsolidated and shrinks by less than 1% during sintering. Molten silicon is flowed into the voids of the unconsolidated sintered body. Chemical vapor deposition or plasma spraying coats onto the cermet structure a protective film of silicon carbide, boron carbide, diamond, or related carbon-based materials. The part may be configured for use in a plasma reactor, such as a chamber body, showerhead, focus ring, or chamber liner.

  • Patent number: 6605316
    Abstract: Provided are low-cost, mechanically strong, highly electronically conductive porous substrates and associated structures for solid-state electrochemical devices, techniques for forming these structures, and devices incorporating the structures. The invention provides solid state electrochemical device substrates of novel composition and techniques for forming thin electrode/membrane/electrolyte coatings on the novel or more conventional substrates. In particular, in one embodiment the invention provides techniques for co-firing of device substrate (often an electrode) with an electrolyte or membrane layer to form densified electrolyte/membrane films 5 to 20 microns thick. In another embodiment, densified electrolyte/membrane films 5 to 20 microns thick may be formed on a pre-sintered substrate by a constrained sintering process. In some cases, the substrate may be a porous metal, alloy, or non-nickel cermet incorporating one or more of the transition metals Cr, Fe, Cu and Ag, or alloys thereof.
