Description

technical field [0001] The invention relates to a diamond coating preparation device, in particular to an integral hard alloy rotary tool diamond coating prepared by adopting an electron-enhanced hot wire chemical vapor deposition (CVD) method to prepare a diamond coating for an integral hard alloy rotary tool. A layer preparation device belongs to the technical field of coating tool preparation. Background technique [0002] With the development of workpiece materials in the direction of lightweight and composite, non-ferrous difficult-to-machine materials such as high-silicon aluminum alloys, titanium alloys, aluminum-based composites, engineering ceramics, and fiber-reinforced plastics are widely used in automobiles, aerospace, and molds. Integral rotary tools based on high-speed steel and tungsten carbide-cobalt (WC-Co) cemented carbide materials, such as twist drills, integral end mills, reamers and taps, and other complex-shaped tools are widely used. However, when th...
