本文着重介绍了EBSD技术的一个新的应用领域。通常,EBSD映射在用于质量保证的不同金属合金上执行,以获得关于颗粒取向、颗粒尺寸和分布的微观结构的信息。相比之下,用EBSD系统确定单晶金刚石颗粒的取向并不是一种常规的方法。因此,这项工作详细描述了EBSD测试序列,并说明了为统计设计准备定向数据的过程。此外,还仔细研究了样品制备、与探测器的对准以及钻石上的分析位置对菊池图案质量的依赖关系,分别与指标率有关。最后,每个测试样品的取向被用于统计设计,以显示晶体取向对金刚石颗粒磨损行为的直接影响。
This paper focuses on a new field of application for the EBSD‐technique. Generally, EBSD‐mappings are performed on different metal alloys used for quality assurance and to get information about the microstructure regarding grain orientation, grain size and distribution. In contrast, the orientation determination of monocrystalline diamond grains with an EBSD system is not a conventional method. Thus, this work describes the EBSD testing sequence in detail and illustrates the preparation of orientation data for a statistical design. Furthermore, dependencies of the sample preparation, alignment to the detector, and the analyzed position on the diamond on the quality of the Kikuchi‐patterns, respectively on the indexing rates, have been scrutinized. Finally, the orientation obtained of each tested diamond sample has been utilized in a statistical design to show a direct influence of the crystal orientation on the wear behavior of the diamond grains.
