Abstract

1,213,821. Electro-forming turbine blades. ROLLS-ROYCE Ltd. April 4, 1968 [April 12, 1967] No.16874/67. Heading C7B. In making a turbine blade, e.g. a gas turbine rotor blade, containing at least one cavity, a metallic shell is electro-plated on to predetermined conductive surfaces of an assembly formed by at least one removable former and at least one insert, parts of the conductive surfaces of the or each former being covered by a resist to prevent deposition of metal thereon and so form apertures in the shell, and subsequently the or each former is removed to form a corresponding cavity in the shell which communicates with the apertures in the shell. The formers may be of plastic, plaster, wax, aluminium or low melting point metal and may be removed by dissolution or melting, the non- metals being rendered conducting by coating or impregnation with graphite carbon or a metal such as silver or copper. Alternatively the former may be of stainless steel withdrawn bodily via the blade root end. The inserts may be of nickelchromium alloy reinforced with fibres such as of carbon or boron and the electro-plated metal may be nickel, cobalt or alloys of these metals with chromium, optionally in combination with another codepositable material which results in a shell of high melting point and oxidation resistance. Typically fibre-reinforced inserts 25, 26 are located in recesses 23, 24 in a wax former 22 so as to protrude slightly from it, the former being made conductive by a graphite coating covered at locations adjacent the leading and trailing edges of the blade form with a photoresist whereby on electro-plating apertures 31 are formed in the blade shell 20 and on removal of the former communicate with the hollow interior of the blade. In a modification Fig.3 (not shown) the inserts 25, 26 are joined by stiffening webs of metal or fibre-reinforced metal extending the length of the blade and the outer webs are flanked by separate removable formers defining with the inserts the surface on which the shell is electrodeposited.
