摘要: 采用溶胶-凝胶法在玻璃表面制备出ZrO2-SiO2薄膜, 然后通过离子交换形成镀膜增强玻璃, 研究了薄膜组成对离子交换增强玻璃的力学和光学性能的影响。利用紫外可见分光光度计、激光椭偏仪、纳米压痕、三点抗弯和能谱(EDX)分析了薄膜结构及性能。结果表明: 所有薄膜均连续均匀, 纯ZrO2薄膜为四方相结构, 含Si薄膜为无定形结构; 薄膜具有较高弹性恢复率(>60%)以及H/E比(>0.1), 有利于强度增强; 随Si含量增加, 可见光透过率增大, 但表面硬度和杨氏模量随之降低; 0.5ZrO2-0.5SiO2薄膜综合性能最佳: 表面硬度为18 GPa, 抗弯强度为393 MPa, 厚度~45 nm时可见光透过率大于85%。

Abstract: ZrO2-SiO2 films of different SiO2 content were deposited on soda-lime glass substrates through a Sol-Gel process, which was followed by an ion-exchange strengthening process. Phase presents, surface morphology and ion-exchange depth were determined by X-ray diffractometer, scanning electron microscope and energy dispersive spectrometer analysis, respectively. The mechanical and optical properties of coated glass were studied. Homogeneous, continuous and dense films are obtained. Pure ZrO2 film belongs to tetragonal structure, while other films with SiO2 have an amorphous structure. ZrO2-SiO2 films with high ratio (H/E≥0.1) and elastic recovery (We≥60%) were thought to be favourable bending strength. Light transmittance increased, while hardness and Young’s modulus decreased with the increasing SiO2 content in films. Typically, chemical strengthened 0.5ZrO2-0.5SiO2 film coated glass exhibited high bending strength of 393 MPa and high hardness of 18 GPa, and a negligible optical loss in visible region for thin thickness (~45 nm).
