Abstract
A surface treatment of electrical contact pieces in electrolytic plants, in particular of machines for the treatment of circuit boards and conductor sheets is discloses, wherein the contact pieces are made of titanium or some other oxidizing and therefore chemically and electrochemically resistant material. To eliminate unwanted metallization of the contact pieces as a result of an inadequate demetallization on account of the insulating oxide layer and in order to enhance protection against wear, an electrically conductive diamond coating is applied at least on the contact-making areas of the contact pieces.
