An apparatus for controlling deposition of material from a plasma transferred wire arc (PTWA) torch within a bore is provided. The apparatus includes a duct and a plurality of cannons. The duct includes a plurality of fluid passageways separated by cross-members. The plurality of cannons are disposed adjacent and downstream from the plurality of fluid passageways of the duct. The flow of fluid issimultaneously directed through all of the fluid passageways and the plurality of cannons and past the PTWA torch in the bore. 本公开提供了种用于控制来自孔内的等离子转移电弧(PTWA)喷枪的材料沉积的设备。该设备包括导管和多个空心管。导管包括由横向元件隔开的多个流体通道。多个空心管设置于导管的多个流体通道的附近，并且多个空心管设置于导管的多个流体通道的下游。流体的流动同时被引导通过所有流体通道和多个空心管并经过孔内的PTWA喷枪。
