Role of Extreme Pressure Lubricants in Boundary Lubrication and in Metal Cutting | Natu

REBINDER et al. 1 have examined the effects of surface-active agents such as mineral oil solutions of oleic acid to alter the creep and fatigue character of metals. Observed changes are attributed to the adsorption of oleic acid by the metal, thereby hastening the strain-hardening of the metal's

Types of Lubrication – Boundary, Hydrostatic, and Hydrodynam

Lubrication reduces friction between the moving surfaces or rolling pairs. Some of the various types include hydrodynamic, hydrostatic, boundary and extreme pressure lubrication. The lubricant also act as a coolant carrying heat away from the sliding surfaces so it ...
