Abstract
Filament wear guides which are characterized by excellent resistance to abrasive filament wear. Also, the method of their fabrication. A chromium surface on a substrate is controllably nitrided. Such nitriding is accomplished thermally. Resulting chromium nitride surface layer is non-particulate and substantially impervious.
