  • Baths and processes for electrodepositing palladium
    Patent number: 4339311
    Abstract: A process for electrodeposition of palladium is described wherein an electroplating bath comprising a palladium(II) compound is employed which electroplating bath is ammonia-free. The bath contains water and an amine of the formula ##STR1## wherein x=0 or 1 and when x=0: ##STR2## and when x-1: R.sup.1 =N(CH.sub.3) (CH.sub.2).sub. 3 NH.sub.2, NH(CH.sub.2).sub. 2 NH.sub.2, NH(CH.sub.2).sub. 2 NH(CH.sub.2).sub. 3 NH.sub.2, NH.sub.2, OH or C.sub.1-4 -alkoxy, R.sup.2, R.sup.3, R.sup.4 =H or CH.sub.3.The amine permits the electrodeposition of palladium at a current density above 2.5 A/dm.sup.2 and the resultant coatings are semi-glossy to glossy and are characterized by firm adhesion and freedom of pores. The coatings have only low internal tensions.
