【Abstract】 Based on the analyses of geometrical characteristics and failure mechanism of diamond film coated tools with complex geometries,the substrate treatment and CVD coating process are studied systematically by taking solid carbide drills as an example to develop suitable technologies of promoting film-to-substrate adhesion strength.This presentation will be beneficial to the manufacturing technologies of diamond film coated tools with complex geometries.The appropriate ways of utilizing these kinds of tools are also put forward in applications for machining abrasive materials such as Al-Si alloy and metal matrix composite.更多还原
