Abstract
A slip ring has a slip ring track with a contact area, the contact area containing a plurality of pores or cavities. A lubricant is held within these pores and cavities and is enclosed by a top coating. When a slip ring brush is sliding over the slip ring track, it rubs off particles of the top coating, therefore opening some of the pores or cavities which release parts of the lubricant contained therein. This lubricant reduces surface friction of the slip ring brush at the slip ring track and therefore further wear, which results in an extended lifetime.
