Rumble,
The only place that does Boron Carbide is BodyCote Diamond Black Inc.
website:
www.diamondblack.com
You can do a search on the forums for the last six months, and I believe BC has been discussed in the General, Knife Reviews & Testing, and Chris Reeve Knives forums-probably be easiest to do a search for username DarrellGLewis (their Director of Market Development-who has participated on the forums).
You can also email him or Ann Spuller (Marketing Manager) about sending a knife for coating.

Very nice folks.
I had the AL and a folder blade coated with BC and chromium for under $30. Price varies with the size of the blade, and any polishing or blasting they have to do to it prior to coating.
btw, AG Russell (1-800-255-9034) is the only place to get the D2 ArcLite
