| 目的 为准确评价风沙冲蚀环境下钢化玻璃表面形貌，描述形貌演化过程，分析形貌损伤机理。方法 进行了钢化玻璃风沙冲蚀损伤试验，利用激光共聚焦显微镜(LSCM)提取损伤表面形貌，利用透光率仪测试钢化玻璃透光率，综合使用分形维数、多重分形谱、透光率表征不同演化条件(冲蚀时间、冲蚀角度)下钢化玻璃表面形貌演化过程，识别冲蚀损伤特征及损伤阶段。结果 不同冲蚀时间下，存在3个损伤阶段——快速增长期、中速增长期和稳定期，前2个阶段分形维数增速和透光率减速较快，稳定期透光率减速较慢，且分形维数将逐渐稳定在最大值(1.875)左右;不同冲蚀角度下，存在2个损伤阶段，中低冲蚀角(≤60°)下分形维数增速和透光率减速较快，高冲蚀角(>60°)下分形维数增速和透光率减速较慢。结论 钢化玻璃表面冲蚀损伤机制为初生损伤和次生损伤，前者由风沙粒子单次冲击造成，后者是在后续沙粒持续冲击下由初生损伤诱发演化产生，前者复杂程度及对可见光的削弱能力大于后者;快速增长期、中速增长期和中低冲蚀角(≤60°)下以初生损伤为主，稳定期和高冲蚀角(>60°)下次生损伤大量增加。 |

| In order to accurately evaluate the morphology of tempered glass surface under wind-sand erosion environment, describe the evolution process of morphology, and analyze the mechanism of morphology damage. In this paper, the wind-sand erosion damage test of tempered glass was carried out. The morphology of the damaged surface was extracted by laser confocal microscope (LSCM). The transmittance of tempered glass was tested by transmittance meter. The fractal dimension, multifractal spectrum and transmittance were used to characterize the evolution process of the surface morphology of tempered glass under different evolution conditions (erosion time and erosion angle). The characteristics of erosion damage and the stage of damage were identified. It was found that under different erosion time, there were three damage stages, rapid growth period, medium growth period and stable period. The first two stages of fractal dimension growth and transmittance slow down faster.And in the latter stage, transmittance slows down and the fractal dimension will gradually stabilize at the maximum (1.875). Under different erosion angles, there were two damage stages. Under low erosion angle (≤60°), the growth rate of fractal dimension and transmittance decrease rapidly, while under high erosion angle (>60°), the growth rate of fractal dimension and transmittance decrease slowly.The erosion damage mechanism of tempered glass surface was primary damage and secondary damage. The former was caused by the single impact of aeolian sand particles, and the latter was produced by primary damage induced evolution under the continuous impact of subsequent sand grains. The complexity and weakening ability of the former to visible light were greater than those of the latter. The primary damage was dominant in the rapid growth period, medium growth period and low erosion angle (≤60°), while the secondary damage increased significantly in the stable period and high erosion angle (>60°). |
