蓝宝石圆顶生产的现状
2019-02-27
蓝宝石具有较高的透射率,较高的耐用性和耐热冲击性,因此是高速导弹系统中透明穹顶元件的理想选择。 蓝宝石圆顶 用于各种导弹系统的导弹正在生产中,但是为了降低成本和改善性能,需要开发制造技术。 主要费用 蓝宝石圆顶 生产正在制造中。
已经表明,研磨至接近完成的尺寸对于降低制造成本和提高成品圆顶的质量很重要。 使用这种方法,可以将与各向异性和地下破坏有关的光学畸变问题降至最低。 地下损伤已显示会降低蓝宝石的强度。 已经量化了地下破坏的深度,并且显示出可以通过抛光后热处理来提高室温强度。
However, the extremely high hardness and brittleness of sapphire make it difficult to obtain defect-free surfaces. The surface/subsurface damages induced by brittle fracture would reduce sapphire's strength and increase the subsequent polishing time. Therefore, the material removal mode, brittle or ductile, plays a vital role in quality control of the machined surface.
