CPC classification number: C25D7/0607
Abstract: The invention relates to a process and an apparatus for electrolytically depositing, in a moving mode, a continuous film of nickel on metal wire for electrical use. The process comprises using an activation bath and a nickel-plating bath in which the current density is reduced in the upstream portion of the nickel plating bath and/or the downstream portion of the activation bath and the acidity of the nickel-plating bath is so regulated as to develop the nickel in the form of strongly adhering globules of small diameter, which completely cover the wire. The reduction in the above mentioned current density and control in respect of the current density profile along the bath may be achieved by acting on the position of the electrodes in the bath and/or by interposing screens between the electrodes and the wire.

Abstract: The invention relates to elements of aluminum, such as bars, sections or apparatus components for forming electrical contacts capable of withstanding mechanical and thermal stressing.The method by which these elements are produced consists in depositing a firmly adhering layer of nickel to the aluminum substrate at least in the contact zone. The quality of the contact is further improved when the nickel-plated element is in contact with a silver-plated element.The elements according to the invention may be used for the production of pin-type contacts and any other devices for making or breaking electrical circuits, such as isolators, circuit breakers and contactors.
Abstract translation: 本发明涉及铝的元件，例如用于形成能够承受机械和热应力的电触头的棒，部件或装置部件。 产生这些元素的方法是至少在接触区域中将牢固粘附的镍沉积到铝基底上。 当镀镍元件与镀银元件接触时，接触的质量进一步提高。 根据本发明的元件可以用于制造销型触点和用于制造或断开电路的任何其它装置，例如隔离器，断路器和接触器。
