Influence of process parameters on growth of diamond crystal on cemented carbide substrates by HFCVD system

► Changes in diamond coating morphology from 0.133 kPa to 6.666 kPa. ► Effect of surface morphology with substrate pretreatments. ► Effect of seeding on the surface morphology. ► Variation of surface morphology with temperature and methane concentration. ► Reaction of cobalt with diamond at different deposition pressures.
