Supersonic particle deposition as an additive technology: methods, challenges, and applications

摘要

This paper presents a review of recent research inventions in the field of supersonic particle deposition (SPD) additive manufacturing (AM) technology. The SPD, also known as cold spray, is a coating technique that has gained popularity recently because of its ability to apply multi-component coatings. The SPD has the potential to revolutionize the global parts manufacturing and logistics landscape. The state-of-the-art, rapidly emerging cold spray manufacturing technology is an alternative to traditional additive manufacturing (AM) based on powder melting. It enables the rapid fabrication of parts that have properties similar to the parts developed by conventional manufacturing. In this paper, the history and process of SPD are explained. A broad background of metallic SPD AM is provided. SPD parameters, including substrate and particle properties, are discussed. Common challenges in creating consistent SPD coatings as well as challenges specific to metal and ceramic SPD are discussed. This paper explores the material science, processes, and performance gain. Several applications of SPD, including nuclear, aerospace, and electrical industries, are discussed.
