...; the roughness range of various machining operations. The behavior of the GCF and CCF, including their Wettability, Interfacial Tension, Surface Energy, and tribological lubrication effectiveness, were studied and compared over these surfaces. The results show that the concentration of cutting fluid and surface...

... mechanical contact rough surfaces surface energy viscoelasticity rough surface asperity viscoelastic adhesion The known models of contact between elastic bodies can be classified under those that only consider mechanical interactions and those that also include the molecular interaction...

...Clint A. Morrow; Michael R. Lovell The stiction forces that exist in microelectromechanical systems (MEMS) are characterized by surface energy and surface roughness. To simulate this contact condition, a three-dimensional fractal surface geometry and an adhesive contact model for a single asperity...

... dimensionless parameters have been identified which represent combinations of surface roughness measures, Burgers vector length, surface energy, and elastic properties. Results are given for the friction coefficient versus normal force, the normal and friction forces versus separation, and the pull-off force...

... molecular configurations surface energy Ising model lubrication disc drives hard discs In a hard disk drive, the magnetic head flies over the disk surface at an altitude (known as head-disk spacing) of a few dozen nanometers to perform reading and writing operations. This kind of relative...

... that there exists an optimum surface energy at which the stability of bouncing vibration and wear durability becomes highest under perfect contact condition. Furthermore, the behavior of the optimum point for several design parameters were made clear. Contributed by the Tribology Division for publication...
