    Lubricants and Additives Affect Spur-Gear Fatigue (1986)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Surface-fatigue tests conducted with AISI 9310 steel spur gears show surface-fatigue life of AISI 9310 steel spur gears increased as much as 400 percent by addition of small amount of phosphorus-type extreme-pressure (EP) additive in lubricant. Antiwear or EP additives either absorbed onto surface or react with surface to form protective coating or surface film. Boundary film provides barrier that prevents contact of metal surfaces and provides low shear strength, which reduces friction coefficient below base metal.
