...We take powdered metal, ceramic, cermets and carbide/matrix and inject it into the plasma effluent, which heats it a bit and accelerates it toward the prepared surface. There it sticks (if we did it right), builds up and can then be used as-is, machined or ground to final dimension and surface finish.
Airplanes would not fly if not for thermal spray coatings. They are heavily relied upon and designed around.
J!m may be describing thermal spray coatings -- but here he speaks the unvarnished truth.
Previously I asked if J!m's operation were the ones coating our F-16's engine tail feathers, and he replied in the affirmative. If you haven't seen what those coatings must contain, check out this pyromaniacs delight showing early evening full afterburner takeoffs:
Here's a close up. No soot, burns hot & clean. (This is the classic 'Italian Tune Up' taken to the next level... :0)
One of my old Block 25 (P&W) gray gals, big picture photo where you can see how the tail feathers look at rest.
My plane + your P&W engine bits = Tip of the Spear. Our mission was to provide non-stop protection for the troops on the ground.
Needless to say, it takes more than a village to make these complex machines work as advertised. Allow me to stop here & thank you for your contributions to keeping my pilots safe during their sorties. Excellence
is appreciated. And your speaker cables were part of the scrap from this support activity? They must kick some serious silver-plated-copper @$$!

Small world, ain't it?
