Abstract
The present invention is directed to a topographical support member which is useful for-producing nonwoven fabrics or apertured plastic films. The topographical support member is a rotatable hollow cylindrical tube having a substantially smooth surface and plurality of apertures therethrough. A substantial portion of the surface of the topographical support member has an ion beam deposited coating, the coating being highly adherent and exhibiting improved wear resistance relative to uncoated topographical support surfaces. The coating layer is deposited on the support member by a beam of ions containing two or more of the elements of C, Si, H, O, or N.
