摘要
硬质材料包括硬质合金、金刚石、氮化硼及其复合材料等,因其高硬度和强耐蚀性等优异特性,在航空航天、汽车制造、医疗器械、能源以及工业工具等诸多领域得到广泛应用。然而,随着复杂形状硬质材料零部件应用需求的日益增长,传统制造方法如粉末冶金技术等面临诸多限制。增材制造技术为此类应用提供了有效的解决方案。本文概述了硬质材料增材制造技术的基本原理并总结了其主要特点,综述了采用增材制造技术制备硬质合金、金刚石、氮化硼及其复合材料等硬质材料的研究现状,探讨了增材制造硬质材料的应用前景,并指出了当前存在的问题及未来的发展方向。
Hard materials,including cemented carbide,diamond,boron nitride,and their composite materials,are widely used in aerospace,automobile manufacturing,medical devices,energy,and industrial tools due to their excellent characteristics such as high hardness and strong corrosion resistance.However,with the increasing demand for the application of hard material parts with complex shapes,traditional manufacturing methods such as powder metallurgy technology face many limitations.Additive manufacturing technology provides an effective solution for such applications.In this paper,the basic principles and main characteristics of additive manufacturing technology for hard materials were summarized,and the research status of hard materials such as cemented carbide,diamond,boron nitride,and their composite materials prepared by additive manufacturing technology was reviewed.Moreover,the application prospects of hard materials by additive manufacturing were discussed,and the current problems and future development directions were pointed out.
