摘要

摘要: 以玻璃为代表的硬脆材料由于其高硬度、高脆性等特点，使其在加工过程中极易出现凹坑、脆性破碎及表面/亚表面裂纹等损伤，严重影响其使用性能和表面完整性。从单磨粒变切深划擦实验着手，研究在单磨粒划擦过程中速度变化对钠钙玻璃表面裂纹生成与扩展以及表面完整性的影响。结果表明：单磨粒变切深划擦实验能够实现磨削过程中的划擦、耕犁、切削3个阶段，且随着划擦速度增加，钠钙玻璃发生脆—塑转换的临界深度增加，划痕形貌及划痕边缘光滑度提升。

Abstract: Due to the high hardness, the high brittleness and other characteristics, the hard and brittle materials represented by glass were prone to damage such as pits, brittle breakage and surface/subsurface cracks during processing, which seriously affected the performance and surface integrity. The effect of velocity variation on the crack formation and propagation and surface integrity of sodium-calcium glass during single abrasive grinding was studied. The results show that the single grain variable cutting depth scratching experiment can realize three stages of scratching, ploughing and cutting in the grinding process, and with the increase of scratching speed, the critical depth of brittle-plastic transformation of sodium-calcium glass increases, and the scratch morphology and scratch edge smoothness increase.
