N2 - ZTA ceramic particle-reinforced high-manganese steel (ZTAP/HMS) composites were fabricated via pressureless infiltration casting with engineered interfaces. A Ni-Mo coating was deposited on ZTA particles by electroless co-deposition to enhance wettability and promote interfacial bonding. The effects of deposition parameters, including temperature, pH, and plating time, on coating morphology and growth behavior were systematically investigated. A dense and uniform Ni-Mo coating was obtained under optimized conditions (80 °C, pH 10, and 5 h), significantly improving interfacial integrity. During composite fabrication, a continuous interfacial transition layer composed of metallic and silicate phases formed through multi-element interdiffusion, enabling the transformation from mechanical interlocking to metallurgical bonding. Heat treatment further induced elemental homogenization and solid-solution strengthening in the high-manganese steel matrix. As a result, the composites exhibited significantly enhanced hardness and wear resistance compared with the unreinforced matrix. The wear resistance of the composite is increased by 3.65 times under SiO2, and 2.71 times under SiC abrasives. The enhanced performance is attributed to the synergistic effects of ceramic load bearing, interfacial strengthening, and microstructural optimization, providing a feasible strategy for designing advanced wear-resistant composites through the interfacial engineering of ceramic reinforcement.
