Monitoring Active Sulfur in EP Gear Oils

Sulfur is used in many EP oils and metalworking fluids as an EP additive. The basic way this works is for the sulfur to react at elevated temperatures, such as those experienced by meshing gears to form a sulfide layer. For example, for steel gears, an iron sulfide layer forms on the gear tooth surface. This ductile layer improves sliding ...
