る。 In the known bath (GB 11 43 178), additives of sulfonic acid and/or its salts are used to create the shine. Specifically, sodium salts of naphthalene-1,5-disulfonic acid, sodium salts of naphthalene-1,3,6-trisulfonic acid, and saccharin (o-sulfobenzoic acid imide) and p-toluosulfonamide, etc. Examples include salts of naphthalene sulfonic acid and aromatic sulfonamides. However, in practice it has been found that the coatings produced by such baths do not meet the requirements from mechanical considerations and even the gloss is insufficient for many decorations. According to the knowledge on which the invention is based, these disadvantages are due to incomplete crystal solution formation. In the present invention, the crystal solution refers to a so-called mixed crystal having palladium atoms and nickel atoms in a crystal lattice.

It consists of one substance or a mixture of these substances: N-pyridinium methylsulfobetaine, N-benzylpyridinium-2-ethylsulfonic acid, sodium salt. If the additives are chosen in accordance with the teachings of the present invention, palladium/nickel coatings can be obtained from the bath by electro-deposition, and these coatings exhibit very fine and uniform crystallites and unhindered crystal solution formation. Excellent. The gloss, elongation and corrosion resistance against various corrosive effects are thereby increased. Furthermore, flatness has also been improved.
