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.

Abstract: A feedback controlled stripping 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 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, and a distillation unit 16 for receiving electrolyte containing dissolved metals from the stripping tank, for purifying the electrolyte received from the stripping tank, and for returning the purified electrolyte to the stripping tank. In a preferred embodiment, the stripping tank 12, the rinse tank 14, and the distillation unit are mounted to a skid 18. The system further includes a control module.

Abstract: The method involves removing wax from a substrate using a non-chlorinated solvent process. The substrate is dipped in a hot wax bath or heated in an oven to remove substantially all of the wax. The substrate is then submerged in either a single or a series of hot mineral oil baths to remove any remaining wax. The oil is then removed by a semi-aqueous or light organic cleaner. The semi-aqueous cleaner is subsequently removed in an alkaline-base cleaner bath. Following the alkaline-base cleaner is a cleansing with a rinsing solution preferably a countercurrent series of rinses. Finally, the substrate is dried.

Abstract: During the manufacturing process for turbine blades and vanes, among other hollow articles, the hollow cavities can become contaminated. Removal of the contaminants is a tedious, time consuming process which commonly results in component rework or rejection. Introducing a foam filler into the hollow cavities, prior to manufacturing, prevents contamination; enhancing manufacturing efficiency and component integrity.

Abstract: A process for selective removal of a nickel alloy brazing composition from a nickel-base alloy component includes the steps of providing a brazed assembly including nickel-base alloy components joined by nickel alloy brazing composition; immersing the assembly in an electrolyte; and applying a potential across the electrolyte at a magnitude wherein the nickel-base alloy components are electrochemically passive and the nickel alloy brazing composition dissolves whereby the brazing composition is removed from the components.
