    Abstract: PROBLEM TO BE SOLVED: To efficiently and cost effectively plate the front ends of aerofoils coated at their blade parts with an insulating material exclusive of their front ends by placing the aerofoils into fixtures and applying a sealant to the aerofoils and the fixtures, then electroplating both. SOLUTION: The blade parts 14 of the aerofoils 10 having route parts 12 and the blades 14 are coated with the insulating material and further, the insulating material is removed from the front ends 16 of the blade parts 14 to expose the front ends 16 to be electroplated. The insulating material is preferably a UV curing the material and is preferably removed from the front ends 16 after the material is cured. The aerofoils 10 exposed with the front ends 16 are placed on the fixtures 20 and are connected via the route parts 12 to electric contacts 32. The fixture assembly is then immersed into a sealing bath and is hermetically sealed and enveloped with a thermoplastic hot-melt coating, etc., while the front ends 16 are held exposed. The fixture assembly is then immersed into an electroplating bath and the electroplating of the front ends 16 is executed.

    Abstract: A process for electroplating a portion of an airfoil comprises the following steps; providing an airfoil having a root portion and a blade portion, the blade portion having a tip remote from the root portion; coating at least part of the blade portion including the tip with an insulating material to produce a partially insulated coated airfoil; removing the insulating material from the tip of the blade portion to be electroplated; mounting the airfoil with exposed tip in a fixture wherein the airfoil contacts an electrical contact; immersing the fixture with airfoil in a sealing bath so as to sealingly encase the fixture and at least a portion of the insulated coated airfoil while leaving the tip exposed to form a fixture assembly with a partial sealant coating; immersing the fixture assembly in an electroplating bath for electroplating the tip of the airfoil; and removing the fixture assembly from the bath. Therefore is used an apparatus for selectively electroplating the tip portion of an airfoil.
