Estimating the term…
The disadvantages of difficulty in operation of the bath and unfavorable physical properties obtained with the simultaneous deposition of metal and a permanent solid lubricant in electroplating baths of conventional composition and containing solid lubricant particles and a perfluorized compound acting as a cationic tenside are avoided if, instead of the perfluorized compound, the bath contains ##STR1## where A.sub.1 -A.sub.9 is H or an alkyl radical with low C number, R.sub.1 -R.sub.9 is H, OH or an alkyl radical with low C number, X is a halogen or SO.sub.4 and n is the valency of X. Preferred solid lubricants are polytetrafluoroethylene, graphite, graphite fluoride or molybdenumdisulfide.
An aqueous electroplating bath containing solid lubricant particles and a water soluble surfactant which, at the pH of the electroplating bath, exhibits cationic properties, for simultaneous deposition of at least one metal and a permanently lubricating solid lubricant, in which, the water-soluble, cationic surfactant is a compound consisting essentially of ##STR7## where A.sub.1 -A.sub.9 is H or an alkyl radical, R.sub.1 -R.sub.9 is H, OH or an alkyl radical, X is a halogen or SO.sub.4 and n is the valency of X.
