Abstract: In this paper, the main principles of laser additive technology are briefly introduced, and the main characteristics of each method are introduced. Secondly, the research status of particle reinforced aluminum matrix composites (PAMCs) in recent years is discussed, and different particle types of reinforcement phase are analyzed. On this basis, the existing difficulties in the research and preparation of particle-reinforced aluminum matrix composites are discussed, including the influence of brittle phase formation on mechanical properties, the difficulty of regulating interfacial reaction, and the high laser reflectivity of aluminum alloy. Finally, the shortcomings of the current research on particle reinforced aluminum matrix composites are summarized, and the future research direction is predicted, that is, further optimization of process parameters and powder ratio, expansion of more process methods, and research and verification in actual production.
Keywords: laser additive manufacturing; aluminum matrix composites; particle reinforced
