Abstract
Frictional and wear properties of zinc di(n-nonylphenyl)dithiophosphate (MA) and di(-di-n-nonylphenyl) dithiophosphate (DA) of n-hexadecane solution in frictional contact of ionic-ZrO2, partially stabilised by Y2O3 (PSZ) tested using a ball-disk tribometer, at 25ºC, have been studied. It was found that zinc dithiophosphates significantly reduce friction and wear. The effectiveness of friction and wear reduction increases with the increasing number of n-nonyl chains of aryl in the additive molecule and with the concentration of additive solution. The sliding speed and load have a detrimental effect on their behaviour. Results of these frictional experiments are closely related to the results of adsorption data of MA and DA on PSZ powder from hydrocarbon solutions.<br/><br/>
