Definitions

  • lit is known to add wetting agents to electroplating baths for the production of nickel, copper or zinc electroplates.
  • 'lhese additives have the effect that the hydrogen which forms at the cathode during the electroplating process is released rapidly and as completely as possible. It the hydrogen remains on the cathode material for longer periods of time it causes an undesirable pore formation in the metal electroplates.
  • the prevention of pore formation is of great importance in the electroplating art in view of the desired corrosion resistance of the metal electroplates.
  • Another task of the wetting agents is to prevent the electrophoretic deposition of small particles of impurities on the metal surfaces, because the corrosion resistance also sufiers from the inclumium baths.
  • Another object is to provide electroplating processes and baths wherein electrodeposits may be obtained which are free from pores and inorganic impurities.
  • Example 11 0.02 to 0.1 gm./liter octyl-phosphoric acid ester was dissolved in a bright chromium-plating bath containing 290 gm./liter CrO When bright nickel-plated objects were chromium-plated in this bath at current densities of 10 to 20 amp/din. and 35 to 40 C., a foam cover of a thickness of about 1 to 2 cm. formed on the bath, which completely prevented the occurrence of chromic acid fogs. The chromium electroplates turned out full-bright.
  • Example 111 When an acid copper bath, which contained 0.25 gm./liter N,N-diethyl-dithiocarbamic acid-n-propyl ester w-sodium sulfonate and 2 gm./liter l-diethylarnino-3- chloropropanol-Z as brightening agents in addition to 200 gm./liter CuSO jl-l O and 60 gm./liter H 80 was modified with 0.01 to 0.3 gm./liter of the compound C12'H25O(CH2CH2O)'1 CH CH C'PO Na and ir-Oll or brass objects were electroplated in this bath within a current density range ofi 0.5 to 7.5 amp./dm. full-bright copper elect-roplates completely free from pores were obtained.
