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.
