Abstract
A method of controlling deposition of material from at least one plasma transferred wire arc (PTWA) torch within at least one bore includes: directing a fluid through a duct; and directing the fluid through a number of cannons N disposed adjacent and downstream from the duct. The fluid is directed through the duct and N cannons and past the PTWA torch while the PTWA torch is spraying downstream from N−1 cannons.

A method of controlling deposition of material from at least one plasma transferred wire arc (PTWA) torch within at least one bore comprising:
- directing a fluid through a duct;
- and
- directing the fluid through a number of cannons N disposed adjacent and downstream from the duct,
- wherein the fluid is directed through the duct and N cannons and past the PTWA torch while the PTWA torch is spraying downstream from N−1 cannons.
A method of controlling deposition of material from at least one plasma spraying torch comprising the steps of:
- directing a fluid through a duct;
- and
- directing the fluid through a number of cannons N disposed adjacent and downstream from the duct,
- wherein the fluid is directed through the duct and the cannons and past the torch while the torch is spraying a surface downstream from N−1 cannons.
A method of applying a coating on a surface of a bore, comprising:
- applying, by a torch, the coating on the surface of the bore;
- directing a fluid through a duct;
- and
- directing the fluid through a plurality of cannons disposed adjacent and downstream from the duct;
- wherein the fluid is simultaneously directed through the duct and all of the plurality of cannons to the bore toward the coating when the torch is applying the coating on the surface of the bore.
