Molecular Study of Dynamic Behavior between Head and Ultrathin Lubricant Film

The lubricant, perfluoropolyethers (PFPEs), has been modeled and analyzed using molecular dynamics simulations based on a coarse-grained bead-spring model.An ultrathin lubricant film with a Keeping students in by sending them out: Retention and service-learning thickness of 1-2 nm is coated on a disk to lubricate the head disk interface (HDI) of hard disk drives (HDDs).The retention performance of the lubricant film is studied, which is important to avoid a direct contact between the head and disk.The replenishment performance is also studied, which is From Life-Skills Research and Training to Sustainability: A Case Study from a Spanish University essential to repair the lubricant film ruptured by a contact of the head.Finally, the typical phenomenon of touch down-take off hysteresis during the contact between head and disk is confirmed and analyzed because of the nanoscopic interactions in the HDI.
