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.
