Tribology and Nano-Tribology Problems in Data Storage on Hard Disks
نویسندگان
چکیده
In current “state of the art” disk drives, the flying height between slider and disk is on the order of 10 nm. The flying height will need to be reduced to approximately 3 nm to meet future storage density goals. At a spacing of 3 nm, severe tribological problems will occur with respect to friction, wear and lubrication of the head/disk interface. In this paper, tribology and nano-tribology problems of the head/disk interface are examined as the recording density is increased towards 1Tbit/inch.

Application of Tribology in Aircraft Engine Sealing Technology
The seals are the important component of the aircraft engine to prevent leakage of gas or oil. Because the contact and friction problems have a great influence on the performance of the seals, the concept and theory of tribology is already widely applied in research and design processes of advanced seals. This report selected three kinds of representative seals which are co...
متن کاملMechanical Application of Lubricated Nano Porous Anodized Aluminium
Today a major environmental problem is global warming that is mainly caused due to exhaust and emission of gases. The only way to reduce their ill-effect is by improvement in fuel efficiency of I.C. engines, where most of the power is lost to overcome the friction. In this work, nanoporous anodized layer is formed on an aluminium substrate surface by anodization. Anodization was carried out at ...

Nowadays it is accepted that the friction force is a combined effect arising from various phenomena: adhesive forces, capillary forces, contact elasticity, topography, surface chemistry, and generation of a third body, etc. Any of them can dominate depending on the experimental force and length scales of the study. Typical forces in macro-tribology are in the Newtons, while are reduced to milli...
