DiaTiger® CVD diamond coating takes place in a vacuum chamber using a hot-filament, chemical vapor deposition (CVD) process. Carbon gases are introduced into the vacuum chamber where high temperatures cause carbon atoms to re-bond into a pure crystalline diamond structure. The crystalline diamond slowly grows on the surface of …

This coating process is very slow, with typical film growth rates of only .5 to 1.5 microns per hour. Since functional coating thicknesses range from 2 to 40 microns, this can mean very long growth cycles of two days or longer. While the typical coating run for a PVD-coated tool is several hours, most diamond-coated tools are in the chamber for ...
