The lattice relaxation in the CVD diamond thick films were detected by the X-ray diffraction attachments. It is associated with self-annealing of diamond thick films in the process of long time deposition. The wearing discrepancy of diamond coated cuttings and diamond thick films brazed cuttings is well illustrated by means of lattice relaxation.

用X射线衍射仪的薄膜附件测试分析金刚石厚膜内的晶格松弛现象，发现沉积金刚石厚膜过程中存在高温自退火的作用，运用晶格松弛的观点很好地解释了金刚石薄膜涂层刀具与厚膜钎焊刀具的耐磨性能差异。
