摘要
Al2O3结构陶瓷具有高强度和硬度且耐磨等诸多优点,但其脆性大,从而制约了其应用。针对Al2O3结构陶瓷的韧化,研究者提出一些增韧机制,主要是采用第二相对其进行韧化,制备Al2O3基复相陶瓷。本文对Al2O3基复相陶瓷的研究进展及其韧化机理进行了综述。
Al2O3 structural ceramic has many advantages such as high strength, high hardness and good wear resistance. But the application of Al2O3 is limited due to its high brittleness. Several toughening mechanisms have been proposed, especially toughening by introducing second phase in Al2O3. In this paper, Research progress and toughening mechanisms in Al2O3 composite ceramic are summarized.
