  • Component produced by additive manufacturing
    Patent number: 10913257
    Abstract: The present invention relates generally to components prepared by additive manufacturing (AM) methods, along with methods of preparing such components by AM. More especially, there is provided a process for the production of a component of an ignition device using an AM method by forming a layer of metal or alloy on a surface of a metal or alloy substrate; fusing the layer to the substrate; and repeating the addition of such layers upon one another to form a deposited metal or alloy attachment on the substrate.

  • Catalyst manufacturing method
    Patent number: 10843174
    Abstract: A method for producing a catalyst or catalyst precursor is described including: applying a slurry of a particulate catalyst compound in a carrier fluid to an additive layer manufactured support structure to form a slurry-impregnated support, and drying and optionally calcining the slurry-impregnated support to form a catalyst or catalyst precursor. The mean particle size (D50) of the particulate catalyst compound in the slurry is in the range 1-50 ?m and the support structure has a porosity ?0.02 ml/g.

  • METAL PROTECTION
    Publication number: 20100218855
    Abstract: Metals for use in glass-making furnaces and which are susceptible to oxidation at furnace operating temperatures, especially iridium or molybdenum, are protected by applying at least (200) microns thickness of a coating formed of metal oxide particles in a metal oxide matrix. Oxidation, measured by weight loss, is significantly reduced.

  • REFRACTORY METALLIC OXIDE CERAMIC PART HAVING PLATINUM GROUP METAL OR PLATINUM GROUP METAL ALLOY COATING
    Publication number: 20100015399
    Abstract: Part of the surface of a metallic-oxide refractory ceramic part, such as a fusion-cast refractory block, is treated using a high energy beam, to remove portions of the surface. A metal film may then be sprayed onto the treated surface of the ceramic part, for example to provide protection against erosion/corrosion in glass furnaces. Excellent adhesion between metal and ceramic can be attained.
