| Abstract: |
| The work aims to analyze the microstructure and surface quality of boron doped textured diamond films, and explore the effects of different textures on the surface of the tool substrate on film bonding strength and cutting performance. Hot wire chemical vapor deposition (HFCVD) was used to deposit boron doped diamond film (BDD) on cemented carbide tools with elliptical texture, groove texture and non-texture on the surface. The surface and cross section morphology of the films were observed by SEM. The surface roughness of each film was detected by white light interference surface three-dimensional profiler. The structure of each film was detected by Raman spectrometer. The cutting performance of each film tool was analyzed through milling test. The roughness of the boron doped non-textured diamond film was 299.9 nm, and the roughness of the boron doped elliptical-textured diamond film and the boron doped groove-textured diamond film was 333 nm and 323.9 nm, respectively, so the roughness slightly increased. The thickness of the three diamond films was 18 μm, and under the same cutting conditions, the degree of peeling of the BDUTD film and the degree of wear of tool were significantly greater than those of BDETD film and BDGTD film after treatment by milling carbon/carbon-silicon carbide (C/C-SiC) composite for 420 s. The textured carbide substrate surface can effectively improve the bonding strength of films, thereby strengthening the wear resistance of the tool. The cutting performance of the boron doped grooved textured diamond film is relatively better. Compared with ordinary boron doped diamond film tools, boron doped textured diamond film tools have a longer service life. |
