  • Patent number: 8999518
    Abstract: The present invention discloses a hierarchical composite material comprising a ferrous alloy reinforced with titanium carbides according to a defined geometry, in which said reinforced portion comprises an alternating macro-microstructure of millimetric areas concentrated with micrometric globular particles of titanium carbide separated by millimetric areas essentially free of micrometric globular particles of titanium carbide, said areas concentrated with micrometric globular particles of titanium carbide forming a microstructure in which the micrometric interstices between said globular particles are also filled by said ferrous alloy.
    Type: Grant
    Filed: August 26, 2009
    Date of Patent: April 7, 2015

  • Patent number: 7935431
    Abstract: The invention concerns a cast wear part with its structure reinforced by at least a type metal carbide, and/or metal nitride, and/or boride, and/or metal oxides, and/or intermetallic compounds, referred to below as constituents. The invention is characterized in that the raw materials used as reagents for said constituents have been introduced in a mould (1) before casting in the form of compacted powder inserts or preforms (3) or the form of slurries (4), and the reaction of said powders has been activated in situ by casting a metal, forming a porous conglomerate in situ, and said metal has infiltrated the porous conglomerate, thus forming a reinforced structure leading to inclusion of said constituents in the structure of the metal used for casting, thereby creating a reinforcing structure on the wear part (2).

  • Patent number: 7513295
    Abstract: A wear part made in a foundry is provided having a structure reinforced with at least one type of metallic carbide, and/or of metallic nitride, and/or of boride, and/or of metallic oxides, and/or of intermetallic compounds, hereafter called components. The raw materials acting as reagents for the components are put into a mold before casting in the form of inserts or preformed shapes of compacted powders or in the form of barbitones. The reaction of the powders is triggered in situ by the molten metal casting, forming a porous conglomerate in situ. The metal infiltrates the porous conglomerate, thereby making a reinforced structure so as to result in inclusion of the components in the structure of the metal used for the casting, thus creating a reinforcing structure on the wear part.
