工程应力分布玻璃研究进展

工程应力分布(engineered stress profile,ESP)玻璃作为一种新型的增强玻璃引起了研究人员的广泛关注.综述了ESP玻璃的理论基础,介绍了ESP玻璃的几种制造工艺及其力学性能.总结了ESP玻璃较传统增强玻璃的优点:强度高,强度分散性低,抗表面损伤能力强及断裂前出现多重裂纹.针对ESP的研究现状,提出了ESP玻璃今后的研究方向:综合其它玻璃增强方法提高玻璃强度,采用微波混合加热或者电场辅助离子交换以缩短处理时间,降低工艺成本.

RESEARCH PROGRESS IN ENGINEERED STRESS PROFILE GLASS

As a novel strengthened glass, engineered stress profile (ESP) glass has attracted extensive attention during recent years. The theoretical basis of the ESP glass was reviewed. The processing and mechanical properties of some ESP glasses were introduced. Compared with the conventional strengthened glass, the merits of the ESP glass (such as high strength, low strength variability, high surface damage resistance and multiple cracking before final failure) were outlined. The combination with other strengthening meth-ods to improve glass strength and microwave hybrid heating or electric field assisted ion exchange used to shorten treatment time and lower cost for processing were proposed to be some aspects on the studies of ESP glass in the future.
