Abstract (en)
[origin: WO2011019667A1] A corrosion resistance system is disclosed that can be used in conjunction with a leaching device for removal of a mold from a cast component. The corrosion resistance system includes a container having a working fluid, such as a caustic fluid. A cast component and mold is placed within the container and a power supply is coupled to the component. During operation of the corrosion resistance system the cast component can be configured as an anode or as a cathode to provide for anodic or cathodic corrosion resistance. In one form the power supply is connected with an electrical conductor to the container and the cast component placed in electrical coupling with the container. An inert gas purge can supply an inert gas to the container. A vacuum pump can be used to remove gas from the container. Furthermore, an oxygen getter can be used in some embodiments.
