Abstract
Metal matrix composites combine excellent mechanical properties and high-temperature resistance, making them essential in aerospace, automotive, and electronics. However, differences in crystal structure and physicochemical properties between metals and ceramics make interfacial bonding critical. This review outlines metal matrix composites fundamentals, preparation methods, and wetting theory, and examines strategies to enhance metal–ceramic interface wettability, including metal coatings, alloying, surface modification, plasma/laser treatments, and pre-oxidation. By integrating theoretical insights and practical techniques, it highlights advancements and future directions for optimizing interfaces, offering guidance for developing high-performance materials with improved durability and functionality in demanding applications.
