PBC anti-scale powder

[Daniel Koster]

are you guys doing any normalizing with the PBC on?

 

[LRB]

Ran three blades today using the PBC anti-scale powder. 20 minute soak at 1500o. Quenched in oil heated to 125o. All came out to perfection. Clean, hard, and no detectable decarb. I am a happy little knifemaker. That PBC is great stuff. Had it not been this forum, I may never have heard of it. Thanks all.

since no1 else stepped forward, I had to do it
The premise of ditching the stainless foil protective
envelopes is just too tempting !

I will report on my findings some time next week.

PCB Special is rated to 2200 (!), is no different in application
than the regular variety (rated to 1650F) and they claim 100%
protection against pitting and decarb....

i would like to see how that works
please keep us updated

 

[Dan Gray]

yes I'm very interested also

Hmmm... thinking...

*whirr*

Processing...

Seems to me that the only thing the PBC Special is good for would be 1095 when going for a hamon perhaps. Other than that, I get such good results with my quench-plates I'm loathe to do it any other way. Perhaps if I make a sword from an air-hardening steel? HT the sword in a forge atmosphere and yank it out to air quench? Lots of possibilities, not at all conventional.

I have used the coating with my damascus and have not had any problems. I use 15N20 and 10XX series steels. I finish out to a 400 grit paper before applying the powder. I have washed off the coating in hot water from the faucet. Use a piece of fine scotch brite (white or gray) and wear rubber gloves to keep the heat off from the hot water. It is like everyone says, it is a time saver.

after reading this, im thinkin about getting some PBC. how long does a pound last? should i be buying the 5lb can?

 

[rashid11]

lasts forever, if you follow my recipe of application:

- get a smallish (3-4") sifter from yer local ShopRite etc
- alum foil @ same place
- Application: heat up the part to be coated to 600F, hold @ that temp for a few mins.
- Put some powder into the sifter
- tear a piece of foil, foot long, lay on the floor/table by the oven
- get the blade out with tongs (long nose plyers, $1.99 @ Harbor Freight, work great)
- hold the blade, via the LNP in one hand, over the foil and use the other and shake the sifter over the blade. Turn the blade and cover the other side too. I usually don't cover the tang area
- put the blade back into the oven
- collect the spilled powder off the foil (lift, bend till crease forms, shake the powder down the crease and into the jar)

the thing's been sitting in me garage for a few days now.
I am conflicting about how I should try it: cut off a smallish
piece of 440c just for test, or do a whole blade

if it will help..

for me because I'm cheap
I'd try it on a blade,, so not to waste the heat..
but leave the blade just a tad thick just in case..
