    摘要： The present invention discloses a hierarchical composite wear component comprising a reinforcement in the most exposed part to wear, the reinforcement comprising a three-dimensionally interconnected network of periodically alternating millimetric ceramic-metal composite granules with millimetric interstices, said ceramic-metal composite granules comprising at least 52 vol%, preferably at least 61 vol%, more preferably at least 70 vol% of micrometric particles of titanium carbide embedded in a first metal matrix, the ceramic-metal composite granules having a density of at least 4.8 g/cm 3 , the three-dimensionally interconnected network of ceramic-metal composite granules with its millimetric interstices being embedded in the second metal matrix, said reinforcement comprising in average at least 23 vol%, more preferably at least 28 vol%, most preferably at least 30 vol% of titanium carbide, the first metal matrix being different from the second metal matrix, the second metal matrix comprising the ferrous cast alloy.

    摘要： The invention relates to a casting insert fabrication method using a composition of powders designed to produce local composite zones resistant to abrasive wear, wherein said composite zones are reinforced with carbides and borides or with mixtures thereof formed in situ in castings, and wherein said powder composition is characterized in that it comprises powder reactants of the formation of carbides and/or borides selected from the group of TiC, WC, , or mixtures thereof, said carbides and/or borides forming after crystallization particles reinforcing the composite zones in castings, and wherein said powder composition further comprises moderator powders in the form of a mixture of metal powders, which after crystallization form matrix of the composite zone in casting. Furthermore, the amount of powder reactants for the formation of TiC carbide is from 3 to 40wt% and the amount of moderator powders is from 60 to 97wt%, the amount of powder reactants for the formation of WC carbide is from 40 to 99wt% and the amount of moderator powders is from 1 to 60wt%, or the amount of the mixture of powders of the reactants of the coupled reaction of the synthesis of TiC and WC carbides is from 10 to 70wt% and the amount of moderator powders is from 30 to 90wt%.
    The invention also relates to a casting insert for the fabrication in casting of local composite zones resistant to abrasive wear, and to a method for the fabrication of local composite zones in castings, using for this purpose the reaction of the self-propagating high temperature synthesis (SHS).
