What is Antiwear Agent [Additive]? What is the meaning for production and application?


Antiwear agent is a kind of additive that can form chemical reaction film on the metal surface to prevent friction surface to generate local sintering in the boundary lubrication condition under high temperature and high pressure (traditionally called this demanding boundary lubrication as extreme pressure lubrication), It’s called extreme pressure additives usually. 


The effect of anti-wear agent is to decompose and react with metal in the high heat of friction, to generate a compound with lower shear stress and melting point than metal, thus preventing to contact surface occlusion and welding melt.
