人造金刚石的冲击强度与其中包裹体含量关系的研究

摘要

研究了金刚石的冲击强度与金刚石中包裹体含量的关系，发现金刚石的室温冲击强度和热冲击强度均随金刚石中包裹体含量的增加而降低，且热冲击强度的下降速率大于室温冲击强度的下降速率。%The relationship between the impact strength and the inclusion content in diamonds have been investigated. It is shown that the toughness index (TI) and thermal tough-ness index (TTI) of diamonds decrease with the increasing of the inclusion content in diamonds, and the decreasing rate of TII is faster than that of TI.
