摘要
The present invention provides tungsten carbide-containing surfaces, and particularly tungsten carbide-containing cutting tools, that are at least partially coated with a thin nanocrystalline diamond film. Also provided are methods for producing the nanocrystalline diamond-coated surfaces. The films are desirably continuous and uniform with a thickness of no greater than about 1 micron. The films may be coated onto the cutting edge(s) of a micro-cutting tool to strengthen the tool, thereby extending its lifetime without significantly increasing the diameter or radius of curvature of the cutting surface.
