Tungsten

NOOOOOOOOOOOOOOOOOO!!!!!!!!!

George,Remember a few years ago I stuck a carbide bit in a billet,it just broke up (even though it welded in) then I couldnt grind the blade,If you want to use diamond wheels you could grind it,but regular belts wont do it.....

If my opinion counts I would say leave it alone...But if you want to be stubborn go ahead and try it,then let us know how it works for you.

I thought that tungsten had a melting point at least twice as much as iron and steel, I thought that it would shrug off the temperature of the forge.
 
Tungsten has a melting point of 6200 degrees...that'd be one hell of a forge weld!
 
I have seen a post were it was tried. When the blade was ground the tungsten did not grind away and left little bumps all over the blade. It could be done with SIC grinding wheel but it would take a very long time. I had the thought also, I have a bottle of powdered W and it has been tempting. I think Vanadium would be better, in fact Vanadium carbides are harder than tungsten....

Im sure there is a way you can make it work,

undoubtly though expect to have a few attempts

either way I wannnna seeeee it!

Once I get to forge welding I want to try it seems like a fairly Unexplored idea in knifemaking but I could be wrong,

either way i still wannnnna seee ittt lol
 
even if it was possible, wouldn't something softer and with higher contrast like nickel be better anyway?

Bruce, ME STUBBORN?????? Give me a break I am a Portagee. HEHEHEHEHEHEHE!
Thanks Guys for the input.:thumbup:
 
I would think that you need the finest powder that you can get, smaller than 300 mesh and it should be cobalt incased for ease of welding...Take Care...Ed
 
Carbide tooling has been sintered with cobalt to provide stability. Tungsten in pure form is extremely brittle. Also if you do get it in a cobalt matrix make sure you grind it with very good protection. Vacuum and respirator are a must as cobalt is toxic. It may take a bit of time to react but you do not want cobalt poisoning. Take years to get over if at all.
The best you can expect I think is capturing the tungsten and holding it in place. If you did not have a fine enough powder it would just chip out and leave a hole in the edge. It would be interesting to see if it would improve the cutting ability. They do use it in O1 so it has to be able to be done somehow.

George, is it tungsten powder or tungsten carbide powder? Two different beasts.
