This also results in excessive consumption of the feces contained in the electroplating bath. A further disadvantage of the established process is the possible contamination of the gold galvanizing solution with cadmium,

The noble metal solution used in the method according to the invention for plating is preferably a hard cobalt-gold solution on the basis of gold cyanide calcium. An example of such a solution is that manufactured by the Sei Rex Corporation of Nutely, New Jersey under the name "Autronex CI Process Solution", but other hard gold solutions are also available and suitable. For the coating of the contact surface of the contact parts 10 which is subject to wear, a hard gold is preferred so that the contact surface is completely protected by a non-corrosive and non-oxidizing metal layer over the entire service life of the connection part in which the contact is installed.

The non-electrical or electroless plating process is an exchange process in which the precious metal, for example essentially pure gold, is thawed out in an ion-plating process against metal of the part to be plated. The thickness of the plating that can be achieved in such a process is limited, for example, to a few hundredths of a millimeter in the case of gold, since the electroless plating process becomes increasingly difficult due to the increasing thickness of the gold deposit on the part. The electroless method is particularly suitable for use in the invention, since the layer thickness la that can be achieved is essentially the same as the layer thickness of the layer which is not thicker from the Wk. Precious metal layer 17 covered parts of the contact to be applied soft gold to prevent later fogging corresponds.
