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.
Claims18
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, the torch being inserted from a first end of the bore;
- directing a fluid through a duct;
- and
- dividing the fluid exiting the duct into a plurality of fluid portions by a plurality of cannons that are disposed adjacent and downstream from the duct and upstream from the torch, each of the plurality of cannons defining a single outlet, only one of the plurality of cannons being inserted into the bore and the only one of the plurality of cannons being inserted into a second end of the bore opposing the first end;
- and
- directing only one of the plurality of fluid portions into the bore toward the coating when the torch is applying the coating on the surface of the bore.
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;
- dividing the fluid exiting the duct into a plurality of fluid portions by a plurality of cannons that are disposed adjacent and downstream from the duct and upstream from the at least one PTWA, each of the plurality of cannons defining a single outlet, only one of the plurality of cannons being disposed into each of the at least one bore, the at least one PTWA torch being inserted into a first end of the at least one bore, the only one of the plurality of cannons being inserted into a second end of each of the at least one bore opposing the first end;
- and
- directing one of the plurality of fluid portions into a corresponding one of the at least one bore and past a corresponding one of the at least one PTWA torch, and a number of the at least one bore within which the at least one PTWA torch is spraying is smaller than a number of the plurality of cannons.
A method of controlling deposition of material from at least one plasma spraying torch comprising the steps of:
- disposing the at least one plasma spraying torch into at least one bore having opposing first and second ends, each of the at least one plasma spraying torch being inserted into the first end of only one of the at least one bore;
- directing a fluid through a duct;
- and
- dividing the fluid exiting the duct into a plurality of fluid portions by a plurality of cannons that are disposed adjacent and downstream from the duct and upstream from the at least one plasma spraying torch, each of the plurality of cannons defining a single outlet, only one of the plurality of cannons being inserted into the second end of each of the at least one bore;
- and
- bore and then past a corresponding one of the at least one plasma spraying torch while the at least one plasma spraying torch is spraying a surface downstream from some of the plurality of cannons.
