Abstract (en)
A slip ring and brush assembly utilizes gold cladding brush wires in sliding or rotating contact with a gold covered slip ring. The metallurgical bonding of the gold cladding to the underlying wire minimizes cracking of the precise metal surface as compared to plated materials while avoiding the high cost of a gold alloy monofilament wire. Other noble metals may be used in place of gold. <IMAGE>
