To provide an apparatus (10, 50) for manufacturing a deposited film (12, 86), and to provide a deposition method thereof and an article (80).
The apparatus (10) includes: a thermal spray gun (16) including a combustion chamber (22); a combustion zone (28); an air injection port (18); a fuel injection port (20); a nozzle (30); and a liquid injection port (34). The combustion zone (28) is positioned between the inlet side (24) and outlet side (26) of the combustion chamber (22). The method includes, among other things, the steps of: providing a fuel and an oxidizer inside the combustion zone (28); initiating combustion inside the combustion zone (28); and directing products of the combustion toward the outlet side (26) to create a combustion product stream. The method also includes the steps of: introducing a feedstock mixture including 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 the nozzle to form the deposited film on a surface of the article.
