<p>Baths are disclosed for electrodepositing bismuth-tin alloys of all ratios as shown by the Figure. The baths are of the acidic alkylsulfonate-type. Soluble bismuth anodes are used to replenish bismuth in the bath solution. The baths find particular use in electrodepositing eutectic compositions such as 58 % Bi-42 % Sn.</p> |
