A method for repairing a structure comprising at least one zone to be heated and which comprises the steps of inflating a frame to form a framework, attaching panels removably to the frame to form an enclosure referred to as a heating enclosure, positioning the enclosure over the zone, heating the interior space of the enclosure using a heating device.

A method of repairing a through-hole formed in a structure having at least one composite material includes filling at least a portion of the through-hole with a potting compound, inserting a portion of a cartridge heater into the through-hole, and curing the potting compound with the cartridge heater.

A method of method of forming or repairing a superalloy article having a columnar or equiaxed or directionally solidified or amorphous or single crystal microstructure includes emitting a plurality of laser beams from selected fibers of a diode laser fiber array corresponding to a pattern of a layer of the article onto a powder bed of the superalloy to form a melt pool; and controlling a temperature gradient and a solidification velocity of the melt pool to form the columnar or single crystal microstructure.

Disclosed herein are embodiments of a plasma treatment system and methods for utilizing directed plasma to reduce instances of gas venting and leaking of contents from plastic bottles due to scratches occurring on sealing interfaces of the bottles and closures. In an embodiment, a plasma treatment system for repairing scratches applied to PET bottles comprises one or more plasma nozzles disposed along a bottle filling line and a plasma being issued by the plasma nozzles to repair the scratches. The plasma nozzles are arranged into a configuration that uniformly distributes plasma to all parts of a neck finish comprising the PET bottles. The plasma treatment of the PET bottles is performed prior to capping of the bottles. In an embodiment, the plasma treatment is performed after filling the bottles with contents so as to avoid a risk of scratches from misaligned filling tubes.
