Composite wear component

A hierarchical composite wear component comprising:

• a reinforced part and a non-reinforced part, the reinforced part comprising a three-dimensionally interconnected network of periodically alternating millimetric ceramic-metal composite granules with millimetric interstices, the ceramic-metal composite granules comprising at least 52 vol % of micrometric particles of titanium carbide embedded in a first metal matrix, the porosity of the ceramic-metal composite granules being lower than 5 vol %, the volume fraction of porosity of the granules embedded in the first metal matrix being determined according to ISO 13383-2:2012;
• wherein the three-dimensionally interconnected network of ceramic-metal composite granules with millimetric interstices is embedded in a second metal matrix, and the volume content of ceramic-metal composite granules in the reinforced part is comprised between 45 and 65 vol %;
• wherein the composition of the first metal matrix is substantially different from the composition of the second metal matrix;
• wherein the second metal matrix comprises the ferrous cast alloy present in the millimetric interstices of the reinforced part, said millimetric interstices additionally comprising at least 1 vol % of micrometric carbide particles selected from the group consisting of tungsten carbide, vanadium carbide, molybdenum carbide, titanium carbide, niobium carbide, hafnium carbide and zirconium carbide, or mixtures thereof, the volume percentage of additional carbides in the second metal matrix being determined according to ISO 13383-2:2012.
