A new CVD diamond coating service for wear parts has been announced by sp3, Inc. The reactors located in Mountain View, Calif., can provide direct coated, smooth diamond films on flat or shaped wear parts. Recently awarded U.S. patents for both process and product are the cornerstones for this new service. Surface finishes as smooth as 0.1 micron Ra can be routinely obtained on finished parts without the need for post deposition polishing. Wear rates and coefficient of friction are comparable to polished large grain diamond films. Such depositions can be accomplished on a wide variety of materials including most metal carbides, silicon carbides, and either polycrystalline or single crystal silicon.
