Title: Electrolytic jet plasma process and apparatus for cleaning, case hardening, coating and anodizing
Inventor: ZHANG JINGZENG
IPC: C25F1/00
Filed: 2004-07-26
Abstract: This invention relates to the plasma process in electrolytic or combinative electrolyte/gas/suspension environments for cleaning, case hardening, coating and anodizing of ferrous and non-ferrous metals and their alloys as well as composites. The plasma process carried on the material surfaces is established by arranging the materials to form the cathode or anode of an electrolytic cell circuit in which the counter-electrode is the electrolytic jet head and the jetted electrolyte is the electrically conductive medium between the electrodes biased by an AC, DC or pulse DC voltage in excess of 100 V. The electrolyte used is an aqueous solution impinged with air/gas into electrolytic flow or incorporated with powder additives into the solution at various percentages.  Without requirement of a large power, the process can be adapted for cleaning, case hardening (i.e., carburizing, carbonitriding, nitrocarburizing and nitriding) and coating (i.e., metallic, ceramic, polymeric and composite) of localized and large conductive material surfaces when the surfaces are as the cathode and for anodizing of lightweight (e.g., Mg, A1 and Ti) metals and alloys when the materials are as the anode.
Patent CA-2474795-A1 (CA)
Inventor: PSCHEIDT EDWARD
IPC: C02F3/34
Filed: 2003-02-04
Abstract: A device and method for disposal of waste fluid comprises directing the wast e fluid having a first osmotic energy potential from a source (25) through a feed tube (20) into a larger mixing chamber (42) located in a body of water having a second osmotic energy potential. Thereafter, water is introduced fr om the body of water into the mixing chamber. Mixing occurs within the mixing chamber between the waste fluid and water from the body of water to form a waste fluid/water mixture, the mixing being driven at least in part by osmot ic energy potential difference between the waste fluid and the water in the bod y of water. The chamber has sufficient length to facilitate substantial mixing of the waste fluid with water from the body of water. The waste fluid/water mixture is allowed to flow into the body of water from an opening in the chamber (50).
