  • Publication number: 20230364578
    Abstract: The invention relates to a reactor and a method for producing a product, wherein the reactor comprises an inner part which is formed at least in part from a porous material comprising a catalyst and in which at least one reactant is arranged to flow into the inner part and after that through the porous material to form a product, a shell structure which surrounds the inner part, a space between the inner part and the shell structure in which the product formed from the reactant in the porous material is arranged to flow out from the reactor, and a heating device for heating electrically the porous material. Further, the invention relates to the use of the reactor.

  • Patent number: 11247269
    Abstract: The invention relates to a method for forming powder particles, wherein the method comprises feeding a start material mixture including more than one constituents in the form of granules into a reactor comprising a reaction zone and a heat source, performing thermal synthesis in the reaction zone in which the start material mixture is moved and the constituents of the start material mixture react in the presence of heat so that the reaction is started by means of heat of the reactor and energy of the start material mixture is released in the form of heat in order to achieve the reaction, and producing powder particles during the reaction. Further, the invention relates to a powder particle product.

  • Publication number: 20200276642
    Abstract: A method for manufacturing a multi-material component, including manufacturing a part with at least one internal channel and/or cavity open to an outer surface of the part with additive manufacturing method, such as selective laser melting, from a first material, filling after manufacturing the part from the first material, the at least one channel and/or cavity in the part with at least one second material, where the open area of the at least one channel and/or cavity at the surface of the part is covered, and subjecting the at least one second material to a hot isostatic pressing in which the part manufactured from the first material forms part of the high-pressure containment vessel for the second material. Further disclosed is such a multi-material component.

  • Patent number: 7637793
    Abstract: A spark plug for an internal combustion engine, the spark plug having at least two electrodes, in which the electrodes are formed of a first part made of a substrate material and a surface part more durable than the substrate material. The surface part of the spark plug is joined to the first part via an intermediate part making use of explosion welding. The method also relates to a method for producing a spark plug for an internal combustion engine, the spark plug having at least two electrodes.

  • Patent number: 6818315
    Abstract: A method for the manufacture of a metal matrix composite by the SHS technique comprises a reaction between titanium and carbon or between titanium and borium, forming titanium carbide or titanium diboride. Tantalum and molybdenum or chromium are blended to the raw materials of the metal matrix composite to improve the resistance of the metal matrix composite to high temperatures and/or corrosion. The invention also relates to a metal matrix composite which contains elements at whose presence a protective oxide layer is formed on the surface of the metal matrix composite during the use.
