冷喷涂增材制造铝基复合材料研究进展

Cold spray additive manufacturing (CSAM), as an emerging solid-state additive manufacturing technique, has demonstrated significant potential in the fabrication of aluminum matrix composites (AMCs) owing to its inherent advantages, including the absence of phase transformation, very limited oxidation, and a very narrow heat-affected zone during the deposition process. This article provides a systematic review of recent advances in the application of CSAM technology for AMCs, with a particular focus on composite powder preparation methods, as well as the influence of process parameters and post-treatment techniques on coating performance. Research indicates that CSAM AMCs exhibit superior wear resistance, corrosion resistance, and fatigue properties, making them highly promising for applications in aerospace, automotive, biomedical industries and so on. Nevertheless, challenges such as inconsistent coating performance, high energy consumption, and insufficient interfacial bonding strength remain to be addressed. Future research should prioritize process parameter optimization, development of advanced post-treatment methods, and exploration of cost-effective spray gases to facilitate the industrial adoption and sustainable advancement of CSAM technology.
