研究了滑块在磁盘表面飞行时润滑块的形成。在本研究中所使用的参数范围内，在100转内形成并达到稳态模式。在此期间，在轨道中没有观察到显著的净润滑剂损失。完成完整的蒙古尔模式之后，润滑剂从轨道上逐渐流失。轨道外厚度的增加并没有弥补损失。据推测，当块体的峰值厚度超过临界去湿厚度时，盘的润滑剂损失开始，因此允许能量有利的过程。本文提出了基于货车范德华相互作用的理论模型。
Presents studies on lubricant mogul formation when a slider flies over a disk surface. In the range of parameters used in this study, moguls form and reach a steady-state pattern within 100 revolutions. During this period, no significant net lubricant loss is observed in the track. The completion of the full mogul pattern is followed by an asymptotic lubricant loss from the track. The loss was not compensated by an increase in thickness outside the track. It is speculated that this lubricant loss from the disk is initiated when the peak thickness of the moguls exceeds the critical dewetting thickness, therefore allowing an energetically favored process. Theoretical modeling based on Van der Waal's interactions is presented.
