摘要： To destructively remove a casting core from a cast part, the part is exposed to a combination of nitric acid and sulfuric acid. The combination may have, by volume, a nitric acid concentration of 4-20 times the sulfuric acid concentration. The combination may be an aqueous solution including, by volume, 40-60% nitric acid and 3-10% sulfuric acid. The method may remove a ceramic casting core and a refractory metal-based casting core. A first leaching step may remove a major portion of the ceramic casting core and may comprise alkaline leaching. A second leaching step may remove a major portion of the refractory metal-based casting core and may comprise acid leaching. The acid leaching may comprise the combination of nitric acid and sulfuric acid.

摘要： The present invention relates to a method for repairing components such as blades used in turbine engines. The method comprises the steps of placing a piece of refractory metal material over an area of the component to be repaired and depositing a repair filler metal material over the piece of refractory material in an amount sufficient to repair the component and welding the repair filler metal material in place. The refractory metal material may be selected from the group consisting of niobium, tantalum, molybdenum, tungsten, a metal having a melting point higher than the melting point of nickel, and alloys thereof and may be uncoated or coated.
