  • Patent number: 9187377
    Abstract: The present invention relates to a process of forming ceramic articles that contain a high percentage of recycled alumina silicate in their composition. The fabrication process includes a fusing of the base material forming a reticulated network that is in-filled with a melted additive composition. The base material gives the article dimensional stability and strength while the additive composition gives the article water resistance and toughness. In this invention, an additive powder with an engineered melting temperature is added to the recycled base material. The mixture is heated until the recycled aluminosilicate reaches the optimal fusing temperature. Heating is continued until the additive begins to melt filling the voids between the fused aluminosilicates particles. The article is then rapidly cooled to quench the fusing without cracking.

    Abstract: A photochemical process for decorating hydrophobic surfaces with nanoparticles includes the steps of providing a metal precursor having hydrophobic parts adapted to interact with assistance of a photosensitizer; and forming a reactive adduct photosensitizer/precursor-metal/surface, preparing the surface to grow metal nanoparticles in situ having sizes and shapes governed by the morphology of the surface. The formed nanoparticles are sufficiently isolated, not aggregated and not interconnected, and do not create a film but maintain the chemical properties of substrate and metal. Surfaces so selectively decorated have hydrophobic properties even with hydrophilic substrates. Substrates with multiple chemical functionalities are thereby obtained, which can selectively bind different molecules or biomolecules onto the substrate and the surface of the metal nanoparticles surface. A process according to the invention also allows decorating surfaces with two or more metallic species.

  • Publication number: 20140193286
    Abstract: In a method for the production of a treatment element for a screw machine, a treatment element core of a first metal material is arranged in an inner space of a capsule of a hot isostatic pressing installation so that a contoured annular space is formed between a capsule wall and a treatment element core. The annular space is filled with a powder of a second metal material so as to produce an anti-wear layer. Afterwards, the treatment element blank is produced in such a way that the materials are combined by hot isostatic pressing to form a composite body. The treatment element blank is then post-processed to form the treatment element. The method according to the invention simplifies the production of treatment elements by in particular simplifying post machining and/or heat treatment of the anti-wear layer thus produced.

  • Patent number: 8679641
    Abstract: A bearing having improved wear resistance has a bearing material of a copper-tin-bismuth alloy which may also include phosphorus which has excellent strength, due to the solid solution of copper, tin and phosphorus (when used), attached to a steel backing shell. The material also has good lubricity as a result of the presence of the bismuth which also promotes tin mobilization and formation of a layer of tin on the bearing surface upon use of the bearing. The addition of small amounts of relatively small hard particles in the copper-tin-matrix, particularly Fe3P, MoSi2 or a mixture thereof, provides a suitable hard surface artifact to improve the wear resistance of the bearing material. The bearing includes a sintered powder compact bearing material of a copper-tin-bismuth alloy powder and a metal compound powder which is bonded to a steel backing shell, wherein the metal compound powder has an average particle size of less than 10 ?m.
