Enhanced properties include optimized wear performance, thermal behavior and sliding friction.
There are many technological methods to improve the tribological characteristics of sliding friction pairs.
Hemphill says that while there is still sliding friction involved, they reduce the amount by about 15% through the use of surface treatments.
The topics include the effect of nanoparticle fillers on transfer film formation and the tribological behavior of polymers, the wear behavior of polyethylene and epoxy composites reinforced with carbon nanotubes, sliding friction and wear in nano-modified and coated rubbers, wear and scratch damage in polymer nanocomposites, and a novel neural network approach to modeling tribological properties of polyphenylene sulfide reinforced on different scales.
Reduction in sliding friction and self-stick tendencies may also be translatable to improvements in catheter design and peristaltic pump tubing.
The exclusive co-axial escapement was the first practical new watch escapement to be invented in some 250 years and its advantages - reduced sliding friction, greater mechanical efficiency, more stable precision and improved shock resistance - have caused the entire watch industry to take notice.
For example, worm or spur type gearboxes are widely used, yet are inherently inefficient - worm gears are at best between 65 and 80% efficient in terms of energy losses as they have high levels of internal sliding friction.
A bigger change is observed for silicone rubber, where the sliding friction against stainless steel drops by 60% when microstructures are added to the surface (Figure 2).
Unlike the conventional Swiss level escapement that triggers a sliding friction between the hidden toothed wheels, the co-axial movement connects the watch's bearings on a mere radial impulse.
