阅读说明：本技术 抗刮玻璃及制造方法 (Scratch resistant glass and method of manufacture ) 是由 J·阿明 郭晓菊 P·奥拉姆 R·V·鲁斯夫 L·尤克雷辛克 T·M·威尔金森 于 2020-03-23 设计创作，主要内容包括：玻璃基制品包括提供改善的刮擦抗性的应力分布。一种玻璃基制品包括：铝硅酸锂组合物；以及在从表面到0.4微米的深度的距离上求平均的二氧化钾(K-(2)O)与二氧化钠(Na-(2)O)的摩尔比,该摩尔比大于或等于0且小于或等于1.8。该制品包括：具有从玻璃基制品的表面延伸到玻璃基制品的一个深度的非零变化浓度的钠；以及尖峰层深,其大于或等于4微米且小于或等于8微米。该制品在从15微米到40微米的深度上可以包括大于或等于150MPa的平均压缩应力。(The glass-based article includes a stress profile that provides improved scratch resistance. A glass-based article comprising: a lithium aluminosilicate composition; and potassium dioxide (K) averaged over a distance from the surface to a depth of 0.4 microns 2 O) and sodium dioxide (Na) 2 O) in a molar ratio greater than or equal to 0 and less than or equal to 1.8. The article comprises: a non-zero varying concentration of sodium extending from a surface of the glass-based article to a depth of the glass-based article; and a peak depth of layer greater than or equal to 4 microns and less than or equal to 8 microns. The article is at a depth of from 15 microns to 40 micronsAn average compressive stress greater than or equal to 150MPa can be included.)
