Tribological Studies on Different types of low saps antiwear additives

Abstract

The efficiency of a mechanical device is strongly reduced due to friction and wear between moving surfaces. Friction and wear are therefore, always undesirable in such applications as these adversely affect the functionality of the mechanical device and limit its life-span. Lubricants play an important role towards reduction in friction and wear between sliding surfaces by interposing a thin film. Over the years, various categories of lubricant additives have been employed for various purposes. To protect the engineering components from wear and tear, antiwear, antifriction and extreme pressure additives have been used along with lubricants. Among these lubricant additives, zinc dialkyldithiophosphates (ZDDP) are being frequently used as excellent multifunctional lubricant additives in lubricant industries.
