铜基体表面 CVD 单晶金刚石微粉的制备
Preparation of CVD microcrystalline diamond powders on Cu substrates
摘要
Abstract
Ultrasonic grinding pretreatment is applied on Cu substrates to deposit microcrystalline diamonds with self-nucleation method by hot filament chemical vapor deposition HFCVD It is show that without ultrasonic grinding pretreatment only a few microcrystalline diamonds can be deposited on the Cu substrate When the duration of pretreatment is about 1 min a large amount of microcrystalline diamonds is deposited on the substrates simultaneously However when the duration of pretreatment is more than 2 min too many diamonds are deposited and there forms a diamond film on the substrate The microcrystalline diamonds deposited by CVD methods exhibit a cubo-octahedral morphology and have the euhedral diamond faces with 111 and 100.关键词
