In order to improve the wear resistance of the shaped compacting dies and the quality of as-produced cables,adopting the hot filament chemical vapor deposition, a type of high-performance diamond film was uniformly deposited on the inner hole surface of the compacting die with a sector-shaped hole that has been optimally designed. Such the diamond film is the boron-doped micro-crystalline, undoped micro-crystalline and undoped fine-grained composite diamond film, which shows favorable adhesion, relatively n...
