中文摘要: 陶瓷增强金属基复合材料(MMCs)因其优异的耐磨性、韧性、高温蠕变性能和疲劳强度,已被广泛应用于生物医学、航空航天、电子等高端工程行业。激光熔覆是在基体表面,利用激光束使陶瓷及其他特殊粉末与基体表层融化,并自激冷却形成冶金结合涂层的环保新技术,具有沉积效率高、厚度可控、热变形小、冷却快、稀释率小以及冶金结合等优点。本文介绍了激光熔覆陶瓷颗粒的形成方式对MMCs性能的影响,随后讨论了激光熔覆辅助能场及高速激光熔覆技术对MMCs的界面强化效应,并分析了陶瓷颗粒的强化机制和激光辅助能场的作用机制。最后,对目前激光熔覆陶瓷颗粒增强基金属复合材料研究的发展进行了展望。
Abstract:Ceramics-reinforced metal matrix composites (MMCs) are widely used in harsh working conditions due to their excellent wear resistance, toughness, high-temperature creep properties and fatigue strength, and have been used in high-end engineering industries such as biomedicine, aerospace, and electronics. Laser cladding is a new environmental protection technology, which melt the powder and the surface of the matrix and self-excite the coating formed by the ceramic and other special powders on the surface of the matrix through laser beams, which has the advantages of high deposition efficiency, controllable thickness, small thermal deformation, fast cooling, small dilution rate and metallurgical bonding. In this paper, the effect of the formation mode of laser cladding ceramic particles on the performance of MMCs was introduced, the interface strengthening effect of laser cladding auxiliary energy field and high-speed laser cladding technology on MMCs was reviewed, and the strengthening mechanism of ceramic particles and the mechanism of laser assisted energy field are analyzed. Finally, the current problems and prospects of laser-clad ceramic particle reinforced metal-based composites are expounded.
