  2. Dry lubricant - Wikipedia

    en.wikipedia.org/wiki/Dry_lubricant

    Anti-friction (AF) coatings are "lubricating paints" consisting of fine particles of lubricating pigments, such as molydisulfide, PTFE or graphite, blended with a binder. After application and proper curing, these "slippery" or dry lubricants bond to the metal surface and form a dark gray solid film.

  3. Friction modifier - Wikipedia

    en.wikipedia.org/wiki/Friction_modifier

    Friction modifiers are added to lubricants in order to reduce friction and wear in machine components. They are particularly important in the boundary lubrication regime, where they can prevent solid surfaces from coming into direct contact, substantially reducing friction and wear .

  4. Fluid bearing - Wikipedia

    en.wikipedia.org/wiki/Fluid_bearing

    Fluid bearings generally have very low friction—far better than mechanical bearings. One source of friction in a fluid bearing is the viscosity of the fluid leading to dynamic friction that increases with speed, but static friction is typically negligible. Hydrostatic gas bearings are among the lowest friction bearings even at very high speeds.

  5. Darcy friction factor formulae - Wikipedia

    en.wikipedia.org/wiki/Darcy_friction_factor_formulae

    In this article, the following conventions and definitions are to be understood: The Reynolds number Re is taken to be Re = V D / ν, where V is the mean velocity of fluid flow, D is the pipe diameter, and where ν is the kinematic viscosity μ / ρ, with μ the fluid's Dynamic viscosity, and ρ the fluid's density.

  6. Floor slip resistance testing - Wikipedia

    en.wikipedia.org/wiki/Floor_slip_resistance_testing

    Slip resistance testing (or floor friction testing) is usually desired by the building's owner or manager when there has been a report of a slip and fall accident, when there has been a report of a near accident, or (preferably) before the flooring is installed on the property. Flooring is tested using a tribometer (floor slip resistance tester ...

  7. Boundary friction - Wikipedia

    en.wikipedia.org/wiki/Boundary_friction

    This "boundary friction" produces various effects, like an increase in lubrication through the generation of shearing forces, or an oscillation effect during motion, as the friction increases and decreases.

  8. American Bearing Manufacturers Association - Wikipedia

    en.wikipedia.org/wiki/American_Bearing...

    The American Bearing Manufacturers Association is an industry trade group that deals with all aspects of bearing technology. It was founded in 1917 as an informal group of manufacturers with the purpose of aiding bearing manufacturing during World War I.

  9. Sensitivity (explosives) - Wikipedia

    en.wikipedia.org/wiki/Sensitivity_(explosives)

    In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. [1] Current in-use standard methods of mechanical (impact and friction) sensitivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type ...
