玻璃渗透温度对ZrO2-玻璃复合陶瓷组织及性能影响
Effect of Glass Infiltrating Temperature on the Microstructureand Properties of ZrO2-Glass Composite
摘要
Abstract
In this paper,the porous ZrO2 ceramic substrate was prepared by microwave sintering.Then,Mg-Al-Si glass powder was coated on the surface of porous ZrO2 ceramic substrate.The effects of different glass-infiltrating temperature on the microstructure,flexural strength and fracture toughness of ZrO2-Glass composite were studied.The results show that the phase structure does not change of ZrO2 ceramic matrix with increasing the infiltrating temperature,still is tetragonal phase ZrO2.With increasing the glass-infiltrating temperature,the density,flexural strength and fracture toughness of the ZrO2-glass composite all first increased and then decreased.At 1 300 ℃ the mechanical performance reaches the best,which the density,flexural strength and fracture toughness are 5.91±0.035 g/cm3,568.870 MPa,14.791 MPa·m1/2,respectively,and compared to the porous ZrO2 ceramic matrix increased by 2.6%,68% and 74%,respectively.关键词
