摘　　要：作为研究最早和应用最广泛的陶瓷材料之一,氧化铝(Al_(2)O_(3))陶瓷具有高强高硬、耐高温、耐磨损、耐腐蚀等许多优异特性,已在国防工业、航空航天以及生物医疗等领域得到了广泛应用。然而,固有的脆性极大地限制了Al_(2)O_(3)陶瓷在众多领域中的进一步应用。增韧始终是陶瓷材料研究中的一个核心研究课题,引入增韧相材料是提高陶瓷材料韧性的主要途径。本文首先简要概述了陶瓷材料的增韧机制,随即综述了Al_(2)O_(3)陶瓷增韧的最新研究现状,分析了增韧方法中存在的关键问题,展望了Al_(2)O_(3)陶瓷增韧的发展方向,以期为后续Al_(2)O_(3)陶瓷增韧的发展提供借鉴。As one of the earliest researched and most widely used ceramics,alumina(Al_(2)O_(3))has many excellent properties,such as high strength and hardness,high-temperature resistance,wear resistance and corrosion resistance,etc.,and has been widely used in the fields of defense industry,aerospace and biomedicine.However,the inherent brittleness greatly limits the further application of Al_(2)O_(3)ceramic in many fields.Toughening has always been a core research topic in the study of ceramic materials,and the introduction of toughened phase materials is the main way to improve the toughness of ceramic materials.In this paper,the toughening mechanism of ceramic materials is briefly summarized,and then the latest research status of Al_(2)O_(3)ceramic toughening is reviewed,the key problems existing in the toughening method are analyzed,and the development direction of Al_(2)O_(3)ceramic toughening is prospected,in order to provide reference for the subsequent development of Al_(2)O_(3)ceramic toughening.
