【Abstract】 By applying the hydrogen and acetone,diamond coatings are deposited upon complex-geometry WC-Co-cemented carbide drilling tools.This process is treated using the electron-enhanced hot filament chemical vapor deposition (HFCVD) and relevant improved CVD equipment.In this study,a new pre-treatment method,together with a new CVD coating process,is investigated regarding the complex-geometry diamond-coated tools.Meanwhile,the cutting test is conducted for SiC-reinforced aluminum-matrix composite materials.From experimental results,it is found that the durability and cutting performance of complex-geometry diamond-coated tools are enhanced.更多还原
