Abstract
In a wrapped ring manufacturing process for slip ring assemblies, the assembly is heated to expand a gap between ends of the slip ring. A conductive material is then used to fill the expanded gap, to assure compression of the conductive material and to eliminate cracks therein. The filled gap is electroplated with a precious metal to form a layer of material of uniform hardness, wear resistance, electrical conductivity and environmental resistance around the entire perimeter of the slip ring.
