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).

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.

Abstract: The present invention relates to a wear part made in a foundry, with 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, characterised in that the raw materials acting as reagents for said components have been put into a mould (1) before the casting, in the form of inserts or preformed shapes of compacted powders (3) or in the form of barbitones (4), in that the reaction of said powders has been triggered in situ by the molten metal casting, forming a porous conglomerate in situ, and in that said metal has infiltrated the porous conglomerate, thereby making a reinforced structure, so as to result in an inclusion of said components in the structure of the metal used for the casting, thus creating a reinforcing structure on the wear part (2).

Abstract: Throw shoe with one or more pockets, which is intended for centrifugal-type crushers with a vertical shaft provided on its working face of a composite reinforcing structure (6) made of wear-resistant ceramic which has been infiltrated by an iron-based alloy and which is created in situ when the throw shoe is being cast.
