<p>Nickel metal matrix composites (NMCs) are advanced materials that integrate nickel with various reinforcements to enhance mechanical strength, thermal stability, and corrosion resistance. This review explores key synthesis techniques, including powder metallurgy, electrodeposition, and additive manufacturing, and their impact on composite performance. The incorporation of nanomaterials such as graphene, carbon nanotubes, and ceramic nanoparticles significantly improves wear resistance, mechanical strength, and thermal stability. Additionally, surface modifications through coatings, such as thermal spraying, electroless plating, and nano-coatings which further enhance functional properties for industrial applications. NMCs find extensive use in aerospace, automotive, biomedical, and energy sectors due to their superior durability and strength-to-weight ratio. Sustainability considerations, including recyclability and eco-friendly processing techniques, are also discussed. Furthermore, artificial intelligence is emerging as a powerful tool for accelerating material innovation by optimizing NMC design, process control, and property prediction. This paper provides a comprehensive review of NMCs, offering insights into their current advancements and potential future directions in intelligent material design and composite manufacturing.</p>
