摘要: Methods and apparatus are provided for plasma-assisted gas production. In one embodiment, a gas, which includes at least one atomic or molecular species, can flow into a cavity (305). The gas can be subjected to electromagnetic radiation having a frequency less than about 333 GHz (optionally in the presence of a plasma catalyst) such that a plasma (310) forms in the cavity (305). A filter (315) capable of passing the atomic or molecular species, but preventing others from passing, can be in fluid communication with the cavity (305). In this way, the selected species can be extracted and collected, for storage or immediate use.

摘要: A method and apparatus are provided for treating the surface of a metal body through phase transformation, ion implantation, and/or diffusion and to form new phases of metallic materials. The method and apparatus have been shown to be particularly useful to improve the hardness and corrosion resistance of ferrous and non-ferrous metals. Generally, the method comprises irradiating a portion of the metal body (18) with a laser (12), and directing a stream of gas (22) onto the same portion of the metal body simultaneously with and preferably for a duration after the laser is turned off. Preferably, the laser (12) is a carbon dioxide laser operated in a pulsed mode to control heating of the metal (18). The gas (22) is preferably carbon dioxide to quickly cool the metal when the laser is off, and to provide carbon atoms for deposition onto the body. The entire process may be carried out in an environment at atmospheric pressure, obviating the need for a vacuum chamber or pressure controlled furnace or similar apparatus. After treatment, the hardness and corrosion resistance of at least a ferrous body are dramatically increased. Advantageously, both sides of a thin metal body, such as a metal tube, may be simultaneously treated. Further, a new, highly oxygenated, hard and extremely corrosion resistant metal phase may be created.
