【摘要】 利用低温离子交换法对高铝硅酸盐玻璃表面进行强化,研究了离子交换温度和时间对高铝硅酸盐玻璃表面应力层深度、表面压应力和显微硬度的影响,及应力层深度和表面压应力对显微硬度的影响。结果表明,第一,随着强化温度和强化时间的增加,表面应力层深度增加、显微硬度增强,但是增速并不均匀。第二,利用SPSS软件得到了应力层深度、显微硬度与强化时间和强化温度之间的关系模型,使用此模型可以预测与样品玻璃有相近组分的高铝硅酸盐玻璃化学强化后的应力层深度和显微硬度。第三,应力层深度较于表面压应力对玻璃显微硬度的增强起主要作用。更多还原

【Abstract】 In order to investigate the effects of chemical strengthening on the surface compressive stress,depth of stress layer and microhardness of glasses,ion exchange experiments were conducted using a high aluminosilicate glass. The results showed that as temperature and time increase, the stress layer becomes deeper and the microhardness becomes higher with asymmetrical rates.Besides,we obtained the dependence of the stress layer and the microhardness on the time and temperature of chemical strengthening technologies,which allows factories to predict the stress layer and microhardness of glasses of similar compositions. It is also found that the stress layer has more significant influence on the microhardness than the surface compressive stress.更多还原
