摘要/Abstract

摘要： 高强度超薄盖板玻璃是电子信息产品的重要组成部分,化学强化(离子交换)是提升超薄盖板玻璃力学性能的主要技术途径。在离子交换过程中,玻璃易产生应力弛豫等现象,导致化学强化玻璃难以具备较高的表面压应力、较大的应力层深度与较高的维氏硬度。本文采用两步法离子交换工艺,研究了熔盐、离子交换温度与时间等因素对强化后超薄铝硅玻璃应力层分布及维氏硬度等性能的影响。结果表明,本文所研发的两步法离子交换工艺,可以使玻璃兼具较高的表面压应力、较大的应力层深度与较高的表面维氏硬度。离子交换后,铝硅玻璃的表面压应力可达900 MPa以上,应力层深度可达70 μm以上,同时表面维氏硬度达7.2 GPa以上。

Abstract: High-strength ultrathin cover glass is an important part of electronic information products, and chemical strengthening (ion-exchange) is the main technological approach to improve the mechanical properties of ultrathin cover glass. During ion-exchange, stress relaxation (structural relaxation) can easily take place, making it difficult for chemically strengthened glasses to simultaneously achieve high compressive stress, large depth of layer, and high Vickers hardness. To overcome this issue, two-step ion-exchange was developed to strengthen aluminosilicate glasses. Effects of molten salts, ion-exchange temperature and duration on the distributions of stress layers and Vickers hardness were investigated. Results demonstrate that high compressive stress, large depth of layer, and high Vickers hardness can be simultaneously achieved via two-step ion-exchange. After ion-exchange, the compressive stress of the glass is over 900 MPa, the depth of layer is over 70 μm and Vickers hardness is over 7.2 GPa.

Key words: ultrathin glass, cover glass, aluminosilicate glass, ion-exchange, compressive stress, depth of layer, Vickers hardness
