Claim:
1. An atmospheric-pressure plasma treatment system, comprising: a plasma source including at least one electrode, a gas in a gas chamber, and an AC power supply that supplies power to the at least one electrode to form a plasma in the gas; and a radial-flow surface having a jet nozzle through which the gas flows, the jet nozzle having a nozzle diameter, wherein the radial-flow surface has a surface profile that conforms to a nonplanar treatment surface of an object, the radial-flow surface separated from the nonplanar treatment surface by a gap that is less than two times the nozzle diameter so that the gas flows radially outward from the nozzle and between the radial-flow surface and the nonplanar treatment surface.
