摘要
冷喷涂作为一种新兴的涂层制备技术,具有沉积效率高、涂层孔隙率低、结合强度高等优点,引起了产业界的广泛关注,在航空航天、汽车、能源、海洋工程、石油和化工等领域有着广泛的应用前景.经过 30 多年的发展,冷喷涂技术的研究已从基础理论研究转变到产业化应用研究,在简述冷喷涂技术原理的基础上,综述了冷喷涂技术在成形机理、材料体系等方面的研究历程;其次,调研了冷喷涂近年来的发展现状,梳理并提出了未来冷喷涂技术向高性能、低成本、增材制造等方向发展的趋势,包括喷涂系统、粉末、工作气体以及离线编程路径设计等方面的改进提升;最后,提出了冷喷涂技术现存的问题与未来发展展望.
Abstract
Cold spray is an emerging coating preparation technology with advantages of high deposition efficiency,low porosity and high bonding strength,which has broad application potential in aerospace,automobile,energy,ocean,petrole-um and chemical industries.The research focus of cold spray has transformed from theoretical research to industrial applica-tion over the past 30 years.Therefore,development history of bonding mechanisms and material systems of cold spray was reviewed in this paper,followed a brief introduction on the principle of cold spray.Furthermore,development trends of cold spray in terms of high performance,low cost and additive manufacturing were summarized,involving improvements of spray systems,powders,working gases and off-line path optimization.Finally,challenges and prospects of cold spray were pro-posed.
