Surface analysis of polycrystalline CVD diamond after static thermochemical treatment

This paper presents a comprehensive surface analysis of polycrystalline CVD diamond after static thermochemical treatment (TCT). The study focuses on subtle changes in the morphology and surface roughness of the diamond before and after TCT. Optical, atomic force, and scanning electron microscopy methods were used to conduct the analysis, allowing for detailed characterization of both macroscopic and microscopic changes. The results show a reduction in surface roughness parameters, significant changes in surface relief and textures, indicating the effectiveness of TCT for such a complex material as polycrystalline diamond.
