COMPOSITE DIAMOND BODY AND COMPOSITE DIAMOND TOOL

摘要

This composite diamond body (10) includes a diamond parent material (11) and a stable layer (12) that is disposed atop the diamond parent material (11). Herein, the stable layer (12) can have a thickness of at least 0.001 µm but less than 10 µm, and can include a plurality of layers. This composite diamond tool (1) includes the composite diamond body (10). This makes it possible to provide a composite diamond body and composite diamond tool having high abrasion resistance and being capable of accommodating mirror surface planarization processing of a workpiece that reacts with a diamond and causes abrasion of said diamond.
