Abstract
The apparatus is particularly intended for depositing chromium on the bearing surfaces of bearings and end stops of turbine rotors made of chromium steel in order to obtain a good coefficient of friction thereon. The apparatus comprises a vat (1) having a vertical axis 00' constituted by a cylindrical portion (2) terminated by a conical portion (3), said vat (1) being filled with electrolyte, first means (7, 8) disposed near the top of said vat (1) for feeding the vat (1) with electrolyte, second means (4) situated at the bottom of the vat (1) for emptying the electrolyte, third means (32, 33) situated between the second means (4) and the first means (7, 8) for regenerating and circulating the electroylte, fourth means (15) for supporting a curtain of anodes (17) made of the metal to be deposited and for rotating the electrolyte about the axis 00', and fifth means (29) for applying current of given polarity to the curtain of anodes (17 ). The apparatus is characterized in that said fourth means (15) are constituted by two cylindrical half-shells (16) about the axis 00', each including a semi-circular frame (18) on which the anodes (17) are fixed parallel to the axis 00', said anode…
