Abstract (en)
[origin: WO9105890A1] In a process for acidic, electrolytic deposition of layers consisting entirely or predominantly of lead on surfaces by means of an electrolyte which contains lead salts and acids, in particular alkane sulphonic acid, fluoboric acid or fluosilicic acid, non-ionic tensides and cationic or ampholytic tensides are added to the electrolyte. The process can be carried out at current densities of 0.5 to 20 A/dm?2 and a pH less than 1.
