| 摘要 |
A method of forming a dual-layer protective overcoat system on a surface of a workpiece, the protective overcoat system being abrasion and corrosion resistant and bondable to a lubricant topcoat, comprising sequential steps of: (a) providing a workpiece including a surface; (b) forming a first, bulk layer of a carbon (C) and hydrogen (H)-containing material on the surface of said workpiece, the bulk layer having a rough and porous upper surface; and (c) forming a second, flash layer of a carbon (C) and nitrogen (N)-containing material on the surface of the bulk layer. Embodiments include forming disk-type magnetic and/or magneto-optical (MO) recording media comprising the dual-layer protective overcoat system and a lubricant topcoat layer.
