In my incessant, insomniac internet inspection, I discovered a company called ASB Industries that offers something called “thermal spray coatings.” Looking into it further, I determined that thermal spray coating is kind of like spray painting on steroids, and it could totally kill you dead.
Apparently, thermal spray coating uses super heated plasma jets (yes, plasma jets—how cool is that? Even if you don’t know what it is, it still sounds rad) to melt any number of materials—like aluminum, stainless steel, ceramic, nickel, etc.—and then blast the molten droplets onto another surface.
Surely it’s all very scientific, but it also sounds very, very dangerous (and don’t call me Shirley).
One little slip up on the job and you’ve covered ol’ Pete in a half inch thick layer of rapidly cooling molybdenum (can’t believe that’s an actual word). Then the shop foreman comes over, calls a few people knuckleheads, tells Pete to stop screwing around and get back to work (even though he’s deader than Viserys Targaryen, and died in much the same fashion), and you’re filling out incident paperwork for the rest of the week.
There are probably a number of useful, um, uses for thermal spray coatings, but it seems to me that the potential hazards involved would perhaps outweigh said usefulness.
