Abstract: A method of repairing service-induced surface cracks (92) in a superalloy component (90). A layer of powdered flux material (100) is applied over the cracks and is melted with a laser beam (98) to form a re-melted zone (104) of the superalloy material under a layer of slag (106). The slag cleanses the melt pool of contaminants that may have been trapped in the cracks, thereby eliminating the need for pre-melting fluoride ion cleaning. Optionally, alloy feed material may be applied with the powdered flux material to augment the volume of the melt or to modify the composition of the re-melted zone.

Abstract translation: 在超合金部件（90）中修复服务引起的表面裂纹（92）的方法。 将一层粉状焊剂材料（100）施加在裂纹上并用激光束（98）熔化，以在一层熔渣（106）下形成超合金材料的再熔化区（104）。 炉渣清理可能已经被捕获在裂缝中的污染物的熔池，从而不需要预先氟化物离子清洗。 任选地，可以使用粉末焊剂材料施加合金进料，以增加熔体的体积或改变再熔融区的组成。

Abstract: A continuous process line for converting hot rolled stainless steel strip to final gauge product is provided. The stainless steel strip has a scale formed on the surface thereof. The steel strip is introduced to a rolling mill to reduce the thickness of the hot rolled stainless steel to a final gauge thickness and tolerance. The rolling mill also cracks the scale on the surface of the final gauge thickness strip. An annealing section anneals the final gauge thickness strip received from the rolling mill. A pickling section pickles the annealed strip from the annealing section and removes the scale from the surface. Preferably, a molten salt bath section provided between the annealing section and the pickling section conditions the scale cracked in the cold rolling section and passes the conditioned stainless steel to the pickling section.

Abstract: A weakly acid solution of either NH.sub.4 NO.sub.3, NH.sub.4 Cl, NH.sub.4 HSO.sub.4, CH.sub.3 COOH or equimolar CH.sub.3 COOH -- CH.sub.3 COONa is employed to remove cores of either Y.sub.2 O.sub.3 or Sm.sub.2 O.sub.3 from castings of advanced superalloy materials. A molten salt bath may be used thereafter to remove reaction products formed by the reaction of the materials of the core and the metal casting.

Abstract: Aspects treat and remove a layer of scale comprising iron oxide and alloying elements oxides that is formed on an advanced high strength metal surface comprising at least two (2) percent by weight of alloy. A first conditioning process compromises structural integrity of or removes iron oxide within the scale layer to expose the alloy oxide to chemical engagement with a disposed aqueous alkali salt solution that is heated to transforming one or more alkali salts within the disposed solution into a quasi-molten form. The alloy oxide is oxidized via reaction with the solution quasi molten alkali salt(s) and water, forming one or more water soluble alkali alloy compounds. A water rinse dissolves and rinses the water soluble compound(s) from the steel product surface of the advanced high strength, leaving a film of iron oxide on the surface that is removed via a final pickling process.
