1. A hierarchical composite wear component, comprising:
a reinforced part comprising a reinforcement of a triply periodic minimal surface ceramic lattice structure, said structure comprising multiple cell units, wherein the triply periodic minimal surface has a continuous curvature both within each cell unit of the multiple cell units and at junctions between two cell units of the multiple cell units, and said cell units comprising voids and micro-porous ceramic cell walls;
wherein micro-pores of the cell walls comprise a sintered metal or a cast metal;
wherein the ceramic lattice structure is embedded in a bi-continuous structure having a cast metal matrix; and
wherein a concentration of the ceramic material in the lattice structure ranges from 30 to 90 vol %.
