Friction and wear pose enormous challenges to 21st Century mechanical and electromechanical systems. By one estimate, 6% of the gross national product is wasted through its impact. Tribology is the ...

The concepts of friction and wear are easy to understand, yet they can interrelate in complex ways within a tribological system (science concerned with interacting surfaces in relative motion ...

Typically, the faster the two surfaces slide past each other, the greater the wear. But at extremely high speeds, comparable to the muzzle velocity of a firearm, this can be reversed: Above a certain ...

Tribology is the science of wear, friction and lubrication which has been utilized in biomedical applications. Medical grade metals and alloys can provide internal support in the body and are employed ...

Oil additives play an essential role in maintaining car engine health. They provide additional lubrication, protect against wear and tear, and help remove impurities and build-up from your engine.

Mechanical engineering is dependent on multiple small components acting together in a system. How these many small parts behave in relation to each other is integral to the functionality of the whole ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Soft knits and brushed fabrics pill most easily, while tightly woven or long-fiber fabrics tend to stay smoother. You can safely remove pills with a fabric shaver, sweater comb, or even tape, ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...
