摘　　要：本文研究了如何利用低温深冷表面处理技术改善ＺＴＭ材料力学性能的问题，实验表明经过适当的低温深冷处理，ＺＴＭ材料的力学性能得到明显改善。抗弯强度和韧性分别提高４０％和４８％。This paper describes how to use the technique of negative-temperature surface treatment for improving the mechanical properties of ZTM ceramics. The experimental results showed that a suitable treatment at negative temperature gave much improved mechanical properties.The room temperature flexural strength σ_f and fracture toughness K_(IC) were increased by 40 % and 48 % respectively.
