Abstract
749,909. Forging; extruding. ROLLSROYCE, Ltd. Feb. 9, 1954 [Jan. 22, 1953], No. 1919/53. Classes 83 (2) and 83 (4). In the hot working of a blank formed from a nickel-chrome alloy, the blank is thinly coated with nickel prior to heating. The hot working may comprise extruding or forging and the nickel coating acts as a lubricant between the blank and the forming dies and protects the surface of the blank from oxidation, thus preventing scale formation and enabling higher working temperatures to be used. The coating is preferably applied by electrodeposition. Making turbine blades.-In the manufacture of a gas turbine blade, a blank of nickel-chrome alloy containing titanium and aluminium, is produced by upsetting, swaging or extrusion and is then machined in a lathe or grinder to provide a good surface finish. The blank is then plated to a depth of 0.001-0.003 inch, heated and forged to shape. The forging may be repeated with reheating. Where the blank is produced by extrusion the metal slug may be coated with nickel prior to extrusion. The nickel coating is subsequently removed by mechanical polishing or by electro-polishing. Working at specifced temperatures.-The hot extrusion or forging operation is performed at a temperature of 1120-1200‹ C. Specification 734,210 is referred to.
