Abstract
A method and assembly for depositing a metal on a cylindrical bore which passes through the central portion of a large part. The invention consists in placing and centering the large part (1) between an upper tank (4) and a lower tank (3), so as to define a chamber (8) inside which the bore (2) is disposed and outside which the peripheral portion (9) of the part (1) extends, said chamber being filled with electrolyte. The electrolyte is homogenized and regenerated continuously by a current which flows between metal anodes (14) in the bore (2) and the part (2) serving as a cathode. The invention is used for depositing nickel on the bores of turbine rotor wheels so as to adjust dimensions or prevent fretting corrosion.
