ABSTRACT:
Flow-through plating apparatus and method particularly effective for the high speed plating and building up of Pb-Sn alloy on bearing shells. An open-ended, flow-through plating cell having a reciprocating anode is provided with a pneumatic electrolyte shuttling system for transferring electrolyte back and forth through the cell in timed relation to the motion of the anode. The surface to be plated is in a recess whose lateral walls are non-conductive to shield the shell ends from overplating.
