利用原子力显微镜（AFM）和氟化物探针观察了PFPE润滑剂在磁盘表面的成膜过程。我们发现，PFPE润滑剂没有均匀地覆盖碳保护表面，而是集中在表面粗糙度的山谷。润滑膜具有一到两个台阶结构，第一台阶高度与分子回转半径基本相同。在销盘试验之后，与初始状态相比，润滑剂台阶高度和覆盖率增加。
We observed how PFPE lubricant film formed to magnetic disk surface using AFM with a fluoride coated probe. We found that PFPE lubricant did not uniformly cover the carbon protective surface but concentrated in valleys of surface roughness. The lubricant film has one to two step structure and the first step height is almost the same as the radius of molecular gyration. After the pin-on-disk test, the lubricant step height and the coverage increased, compared to the initial state.
