PCT No. PCT/EP90/01670 Sec. 371 Date May 29, 1992 Sec. 102(e) Date May 29, 1992 PCT Filed Oct. 5, 1990 PCT Pub. No. WO91/05890 PCT Pub. Date Mar. 2, 1991.A process for acidic electrolytical deposition of lead layers and predominantly lead-containing layers onto surfaces using an electrolyte containing lead salts and acids, in particular alkanesulfonic acid, borofluoric acid or silicofluoric acid, with non-ionic surfactants and cationic or amphoteric surfactants being added to the electrolyte. The process can be operated at current densities of from 0.5 to 20 A/dm2 and at a pH value below 1.
