Have no knowledge about this dry lube. Sounds interesting. One concern would be flash temperature, if you egnight magnesium, you can't extinguish the fire. Think vintage camera flash bulbs.
That one sounds interesting. I burnish molybdenum disulfide powder into my compression tube, piston, and seal. The powder is compatible with Krytox so I use that, too. If I recall correctly, tungsten disulfide is an even better lubricant.
Yes ... sarcastic with a smile Would not shooting a PCP be a whole lot less work and frustrating ?Tho on this note, the smoothest shooting and most consistent spring piston guns I've ever built have been those that assembled with Tight tolerance having buttoned or wear ringed pistons, well fit piston seals and spring guides with a liner in piston running on a OIL FILM only !! Not a stitch of Grease, moly or tar anywhere in the firing mechanics.

I was trying to help honestly .... my last part of above post was some key info if you can do so Yes we all have fun tinkering and doing what we can with what we have to work with.As you were Sir
Finely divided metals (airfloat) will burn fiercely at low ignition temperatures. Most materials considered non-flamable if finely divided will also burn vigorously. For examples, search for pyrotechnic compounds. Quote from: MartyMcFly on February 23, 2021, 02:53:58 PMQuote from: condor22 on February 23, 2021, 02:38:39 PM Have no knowledge about this dry lube.

With fine powders there is a danger of combustion. This is the reason I don't necessarily want a film coating of the stuff on the comp tube walls. There is certainly a concern that as a film on a smooth surface most of it would slush-off with repeated piston strokes and provide aerosolized fuel in the compression chamber (BAD!!!). This is why I like the idea of burnishing it into micro sized abrasions in the steel, that way it stays put. Another idea I had is to only treat the backwards portion of the comp tube. This would reduce initial piston stroke friction while keeping it safe from the heat/pressure that builds up in the forward portion of the compression chamber.-Marty
This appears to be complex CERAMIC COATING that can be applied and bonded to a substrate by pulsed laser deposition or sintering. The discussion of applying this as a home tune lubricant like a grease, molybdenum disulfide powder, or tungsten disulfide powders has me baffled.https://en.wikipedia.org/wiki/Aluminium_magnesium_borideYES, the material does have some impressive characteristics and it MIGHT be useful on some springer parts during manufacturing. That depends on the added cost of the material and its application process. It also depends on how much it actually improves performance over the more common lubrication materials. I'm skeptical that it can make a "significant" difference when used inside a springer.https://en.wikipedia.org/wiki/Friction#Approximate_coefficients_of_frictionhttps://www.lowerfriction.com/pdf/8.pdf
