Synthesis of multifunctional microdiamonds on stainless steel substrates by chemical vapor deposition

We report on the synthesis of multifunctional microdiamonds by chemical vapor deposition (CVD) 304 and 316 austenitic stainless steel (SS) substrates. The increase in wettability achieved surface scratching structure ultra-dense Q-carbon high nucleation density minimized strains diamond films. Notably, these films exhibit a amount twinning, leading to formation five-fold microdiamonds. diamonds scratched SS substrate interlayer full width at half maximum 8.25 cm−1 11.5 cm−1, compared 26 bare substrate. grown exhibited cracking due tensile stress 2.3 GPa, ascribed thermal mismatch between diamond. electron backscattered diffraction investigations reveal iron inclusions synthesized substrates, which may create ferromagnetism diamonds. This route, ion beam implantation method using ferromagnetic ions, yields better samples. At 800 °C, 1012 Fe atoms/cm2s are transferred from into dominant growth orientation for CVD was determined be <110> out plane. These useful biomedical, electronic, tribological applications.
