摘要

本文研究了未掺杂和掺杂tin的ZrB2陶瓷材料在1800℃、15 MPa、1小时热压下的致密化行为和力学特性(断裂韧性和维氏硬度)。在ZrB2中添加5 wt%的TiN可使其相对密度从83%提高到90%。通过晶相分析和微观结构研究,证实了通过与TiN的化学反应去除B2O3等氧化物污染物,并形成新的二次相,如ZrN, h-BN和(Zr,Ti)B2固溶体。致密化的改善和晶粒生长的限制导致了力学特性的增强。维氏硬度和断裂韧性的测量值分别由7.8 GPa和1.5 MPa提高。m1/2至14.1 GPa和3.8 MPa。分别m1/2。

Influence of TiN addition on densification behavior and mechanical properties of ZrB2 ceramics
In the present work, densification behavior and mechanical features (fracture toughness and Vickers hardness) of undoped and TiN-doped ZrB2 ceramic materials, hot-pressed at 1800 ºC under 15 MPa for 1 hr, were studied. The addition of only 5 wt% TiN into ZrB2 has resulted in an increase in its relative density from 83% to 90 %. Removal of oxide contaminations like B2O3 via chemical reactions with TiN and new secondary phases formation such as ZrN, h-BN, and (Zr,Ti)B2 solid solutions were approved employing crystalline phase analysis and microstructural studies. Improvement of densification and restriction of grain growth caused enhancement of mechanical characteristics. The measured values of Vickers hardness and fracture toughness are ameliorated from 7.8 GPa and 1.5 MPa.m1/2 to 14.1 GPa and 3.8 MPa.m1/2, respectively.
