Abstract (en)
The method of electrotinning comprises the steps of:(a) forming a tin plating layer on surface of metallic material (3) by applying direct current between an insoluble anode (6)(6') and the metallic material (3) which are placed in the electrotinning tank (1);(b) applying direct current between the anode (8) and the cathode (9) which are placed in the electrolytic tank (7);(c) controlling a tin deposition rate onto the cathode of the electrolytic tank to keep lower than a metallic tin dissolving rate of the anode, a dissolved tin ion being fed to the electrotinning solution in the electrolytic tank by suppressing a tin deposition reaction and by enhancing a reducing reaction of hydrogen generation on the cathode; and(d) supplying the electrotinning solution supplied with the tin ion at the electrolytic tank to the electrotinning solution in the electroplating tank.
