# Mixture of fuel and oxygen is injected into the combustion chamber.
# Powder feedstock is introduced into the chamber.
# Nitrogen gas is added between the fuel-oxygen mixture and powder feedstock in order to prevent backfiring.
# Mixture is ignited, and heated powder is ejected from the barrel onto the target material.
# Barrel is then purged by nitrogen gas ready for firing again.
# This process is repeated at a rate of between 1–10 Hz until desired thickness of coating is achieved.
