摘要
铜的电学和热学性能十分优异,且具备良好的延展性,因此在航空航天、微电子、轨道交通、通讯等领域有非常广泛的应用。然而,纯铜的机械性能和高温稳定性较差,难以满足日益严苛的应用需求。为改善其机械性能,一种有效方法是将陶瓷颗粒作为增强相添加至铜基体中。本文主要总结了陶瓷颗粒的主要类型,讨论了陶瓷颗粒增强铜基复合材料的制备工艺和研究现状。最后,结合研究现状对未来的研究方向和发展趋势提出了一些见解。
Copper exhibits excellent electrical and thermal conductivity,as well as good ductility,making it widely used in aerospace,microelectronics,rail transportation,communication and other fields.However,the mechanical properties and high-temperature stability of pure copper are poor,making it difficult to meet the increasingly stringent application requirements.An effective method to improve its mechanical properties is to add ceramic particles as reinforcing phases to the copper matrix.The main types of ceramic particles and the preparation process,and research status of ceramic particle reinforced copper-based composites were summarized.Finally,based on the current research status,some insights were proposed for future research directions and development trends.
