Kromplettering fra bad katalysert med alkandisulfonsyre- og alkansulfonsyre-forbindelser med inhibitorer så som aminoalkansulfonsyre og heterocykliske baser

摘要

C1-C18 Alkylsulfonic or Alkyldisulfonic compounds and Aminoalkilsulfonic acids or salts thereof, are used as additives in chromium plating baths to reduce anodic corrosion, improve the covering and penetrating power of the bath, reduce the surface-tension and give a bright deposit.
