CHROMIUM PLATING FROM BATHS CATALYZED WITH ALKANEDISULFONIC-ALKANESULFONIC COMPOUNDS WITH INHIBITORS SUCH AS AMINEALKANESULFONIC AND HETEROCYCLIC BASES

摘要

C1-C12 Alkanesulfonic or Alkanedisulfonic compounds and Aminoalkanesulfonic 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.
