Abstract:
Different types of apparatus for fabricating a deposit, method of deposition and an article are presented. The apparatus include a thermal spray gun comprising a combustion chamber, combustion zone, an air injection port, a fuel injection port, a nozzle and a liquid injection port. The combustion zone exists between the inlet side and outlet side of the combustion chamber. The method includes, among other things, providing a fuel and an oxidizer inside the combustion zone, initiating combustion inside the combustion zone, and directing products of the combustion toward the outlet side to create a combustion product stream. The method also includes introducing a feedstock mixture comprising a feedstock material and a liquid into the combustion product stream to create an entrained feedstock stream, and expelling the entrained feedstock stream from the spray gun through a nozzle to form a deposit on a surface of the article.
