In this paper, the influence of the electric field on the dip-coating process was studied by using lubricants Z-tetraol and TA-30. The electric field assisted the adsorption of both lubricant molecules on the disk surface. This electric field also resulted in an increase in the lubricant film thickness. A positive electric field increased the bonded ratio of the lubricant film. The surface-free energy, step height, and head-disk clearance of the Z-tetraol lubricant film were not affected by the… CONTINUE READING
