    Abstract: THE PRESENT INVENTION RELATES TO A COMPOUND, NON-CHROMIUM CONVERSION COATING FOR A PART FORMED AN ALUMINUM ALLOY. THE COATING IS FORMED BY PROVIDING A FIRST SOLUTION CONTAINING AN ANODIC INHIBITOR SPECIES, PROVIDING A SECOND SOLUTION CONTAINING A CATHODIC CORROSION INHIBITOR SPECIES,A ND IMMERSING THE PART TO BE COATED INA FIRST ONE OF THE FIRST AND SECOND SOLUTIONS AND THEREAFTER IN A SECOND ONE OF THE FIRST AND SECOND SOLUTIONS. SUITABLE ANODIC INHIBITOR SPECIES INCLUDE TUNGSTATES, PERMANGANATES, VANADATES, MOLYBDATES, AND MIXTURES THEREOF. SUITABLE CATHODIC CORROSION INHIBITORS INCLUDES COBALT, CERIUM, OTHER LANTHANIDE ELEMENTS, AND MIXTURES THEREOF. IN ONE EMBODIMENT, THE CONVERSION COATING IS FORMED USING A CERIUM CONTAINING SOLUTION AND A TUNGSTATE CONTAINING SOLUTION.

    Abstract: La presente invencion se refiere a un revestimiento compuesto de conversion sin cromo para una parte formada a partir de una aleacion de aluminio. El revestimiento se forma al proporcionar una primera solucion que contiene una especie inhibidora anodica, proporcionar una segunda solucion que contiene una especie inhibidora de corrosion, catodica, y sumergir la parte que se va revestir en la primera de la primera y segunda soluciones y posteriormente en una segunda de la primera y segunda soluciones. Las especies inhibidoras anodicas adecuadas incluyen tungstatos, permanganatos, vanadatos, molibdatos y mezclas de los mismos. Los inhibidores de corrosion catodicos adecuados incluyen cobalto, cerio, otros elementos de lantanidos y mezclas de los mismos. En una modalidad el revestimiento de conversion se forma usando; una solucion que contiene cerio y una solucion que contiene tungstato.

    Abstract: THE PRESENT INVENTION RELATES TO A FEEDBACK CONTROLLED STRIPPING SYSTEM WITH INTEGRATED WATER MANAGEMENT AND ACID RECYCLING SYSTEM. THE SYSTEM COMPRISES A STRIPPING TANK (12) CONTAINING AN ELECTROLYTE BATH STRIPPING SOLUTION FOR REMOVING A COATING FROM AT LEAST ONE WORKPIECE IMMERSED IN THE STRIPPING SOLUTION WHILE A CONTROLLED ABSOLUTE ELECTRICAL POTENTIAL IS MAINTAINED ON THE AT LEAST ONE WORKPIECE WITH RESPECT TO A REFERENCE ELECTRODE (20) ALSO IMMERSED IN THE STRIPPING SOLUTION, A RINSE TANK (14) FOR RINSING THE WORKPIECE(S) AFTER REMOVAL OF THE WORKPIECE(S) FROM THE STRIPPING TANK (12), AND A DISTILLATION UNIT (16) FOR RECEIVING ELECTROLYTE CONTAINING DISSOLVED METALS FROM THE STRIPPING TANK (12), FOR PURIFYING THE ELECTROLYTE RECEIVED FROM THE STRIPPING TANK (12), AND FOR RETURNING THE PURIFIED ELECTROLYTE TO THE STRIPPING TANK (12). IN A PREFERRED EMBODIMENT, THE STRIPPING TANK (12), THE RINSE TANK (14), AND THE DISTILLATION UNIT (16) ARE MOUNTED TO A SKID (18). THE SYSTEM FURTHER INCLUDES A CONTROL MODULE. A PROCESS FOR USING THE SYSTEM TO REMOVE A COATING FROM A WORKPIECE IS ALSO DESCRIBED.(FIG 6)

    Abstract: During a material removal method, a component (10) is received that includes a component body (12) and a coating (14) on the component body (12). The component body (12) includes metallic first material. The coating (14) includes second material that is different from the first material. A solution (16) is received that includes nitric acid and hydrogen peroxide. At least a portion of the coating (14) is subjected to the solution (16) in order to remove at least some of the second material from the component (10).

    Abstract: The present invention relates to a compound, non-chromium conversion coating for a part formed from an aluminum alloy. The coating is formed by providing a first solution containing an anodic inhibitor species, providing a second solution containing a cathodic corrosion inhibitor species, and immersing the part to be coated in a first one of the first and second solutions and thereafter in a second one of the first and second solutions. Suitable anodic inhibitor species include tungstates, permanganates, vanadates, molybdates, and mixtures thereof. Suitable cathodic corrosion inhibitors include cobalt, cerium, other lanthanide elements, and mixtures thereof. In one embodiment, the conversion coating is formed using a cerium containing solution and a tungstate containing solution.
