摘要:
An amorphous carbon coated tool includes a base material of WC base cemented carbide, and an amorphous carbon film formed on this base material. The cobalt content in the base material is at least 12% by mass. The maximum thickness of the amorphous carbon film is at least 0.05 μm and not more than 0.5 μm at the cutting edge. The amorphous carbon film is deposited with graphite as the source material by physical vapor deposition in an atmosphere substantially absent of hydrogen. The amorphous carbon film coated tool superior in wear resistance and adhesion resistance is preferably applicable to rotating tools such as drills, end mills and reamers, indexable inserts used for milling cutters and turning tools, and cutting-off tools such as cutters, knives, or slitters.
