Abstract
The bath is free of cyanide and contains the gold in the form of a thiosulphato complex. In this bath, gold is electrodeposited as a levelling, non-porous layer at pH values between 4 and 13 and at temperatures between 10 and 80 DEG C with a current between 0.1 and 2 A/dm<2> onto a suitable substrate.
