Boron Carbide Coatings

Ray

One of Bodycote's test is to Rockwell through the coating
and look at it under the microscope for cracking or peeling.
If you were to hit it with a ball peen hammer and only deformed
the substrate the coating will be deform also.
If you abuse or remove the base material the coating will be
removed with the blade material.
At only 2 microns boron carbide can withstand great amount of force without debonding.
But all Thin Film Coatings need backing or a hardend base material for support.

One reason we cannot coat soft materials with Boron Carbide, is the
Egg Shell Effect Very hard on the outside but nothing to support it.

During a conversation with Jeff Carr at Bodycote K-tech taday
we discussed chemically form ceramics and their use around food.
The ceramic coating is Chromium Oxide which is chemically inert
and safe to use for food preperation.

Here is a picture of a BC coated D-2 Blade, this finish goes well with many different handle materials, in this case unwoven carbon fiber. The more I use this coating the better I like it! You can see this knife at the New York Show this comming weekend as well as a couple other BC coated knives on Les Robertsons table.

Darrel, I recently bought a CRKT Apache II that has a black-coated blade that gives a definite metallic, or jeweled effect, very different from any of the coated BM's or MT's I've owned...and quite attractive. Do you know anything about this coating? Or, indeed, are you coating blades for CRKT?
 
Darrel,
Is this process compatable with existing permanantly attached handled knives like my Falkniven F1?
It has a black blade that scratches way too easy.
Where in NC are you, i'm in Southern Pines
thanks
Scott
 
nuggett, Darrell is at the New York Custom show and although I am certainly not his spokesman I can answer your question. No, the handles can not be attached for coating.
 
Rob,
thanks for replying.
I understand then, that I cannot get my F1 coated because it has a permantly attached handle? The blade needs to be stripped?
 
The blade will need to be stripped to bare metal and the handle can not be attached. Think very clean and only blade metal!
 
alright guys

My name is Ann and I work for Darrell. I know of little Timmy's problem and have donated my salary for the year to help fund his operation. Harley, you are so very thoughtful to bring this terrible disease to the attention of the Blade Forum members as I know they are genuinely concerned.

P.S. Darrell says the disease is hereditary.
 
Oh my, I feel really bad for little Timmy! Therefore I volunteer to donate Darrell's salary for the next year to the Timmy fund! I cant imagine having penalacromegleyopticrectitus and walking around with a bloody callus. :eek: I am also sorry to hear it is hereditary and feel sorry for Timmy's mother! :D
 
Larry and Rob Thanks for thinking of Timmy as you know we have been trying to raise money for the operation but last weekend I thought
it would be nice to take Timmy with me to New York to see the Marathon. Timmey wanted to run. I'm sorry to say at the 10 mile mark
another runner stepped on Timmy's DICK and he fell and hit his head.
Now Timmy is in a comma and his family is worried sick.
 
That is terrible news Darrell! Now not only is poor little Timmey in a coma he also needs the reversal of the dreaded addsomedicktome operation! Terrible terrible! :eek:
