摘要
硬质合金因具有高强度、高硬度及高抗氧化性等优势在航空航天、石油矿山及切削加工等领域得到广泛应用。但由于其制备工艺复杂、可加工性能差,使硬质合金的应用发展受到一定程度的限制。激光加工技术因具有高能、快速、精准等优点可弥补硬质合金上述问题的不足。近年来,激光加工技术在硬质合金制造和改性中取得了显著发展,极大拓展了硬质合金的应用潜力。文本综述了硬质合金激光增材制造、激光表面改性、激光辅助加工及激光去除加工技术的研究进展及应用情况,并对硬质合金激光加工技术未来的研究方向提出了展望。
Cemented carbide has been widely used in aerospace,petroleum mining and machining fields for the outstanding characteristic of strength,hardness,and oxidation resistance.However,the application and development of cemented carbide are restricted partly by the poor machinability and complex process of preparation.Laser processing technology has the advantages of high energy,fast and accurate,which can cover the above shortage.In recent years,laser processing technology has shown significant promotion in the manufacturing,modification and processing of cemented carbide,which has greatly expanded its potential.This paper reviews the research progress and application of laser additive manufacturing,laser surface modification,laser-assisted processing and laser removal processing of cemented carbide.And the future direction of laser processing of cemented carbide is discussed.
