Abstract
The invention provides spinning rings for textile spinning processes having an improved bearing surface formed of a coating of amorphous chromium that is typically applied by an electrodeposition process. The amorphous chromium coated spinning rings of the present invention impart a durable spinning ring that can be used in fine yarn, high speed spinning operations without the need to provide for a conventional break-in period.
