Test coupon, OTOH, half the powder came off. Going to be a long day.

Used to do thermo spray coating. Flame spray molten metal on to parts. Used Metco 6Pgun and I can't think of the other one. Also plasma sprayed with Metco 12E gun. Everything we sprayed had a test block that we had to check the hardness on. If the hardness was too soft. We had to machine off the coating and respray the part. I enjoyed doing that type of work.
