Gravure de la rugosité des cylindres de laminoir par impulsions laser

Enhancing tribological performance of the magnetic tape/guide interface by laser surface texturing

“…This, in turn, increases the load carrying capacity for such bearings and reduces the friction coefficient for a constant load. The LST technique has been successfully used in a number of applications, as, for instance, in the manufacturing of metal rolling cylinders with well-defined surface roughness [11] or the fabrication of laser bumps in the landing zone of a hard disk drive to facilitate contact start/stop of the magnetic head [12]. It was, however, not until 1996 that LST was used in conventional lubrication situations as a method to reduce friction and optimize lubrication [13].…”
