dithiophosphate de zinc.
Understanding the true interfacial mechanisms involved in the growth of tribofilms generated by Zinc Dialkyl Dithiophosphate (ZDDP) is important because it is the most widely used anti-wear additive and there is legislative pressure to find efficient environmentally-friendly replacements. The main focus of this study is to investigate the ...
The role of zinc polyphosphate in the antiwear mechanisms of zinc dithiophosphate (ZDDP) is investigated in the light of recently published analytical data carried out on thermal films and tribochemical films obtained from the additive. Special attention is paid to explaining the mechanisms of the polyphosphate in eliminating abrasive wear due to the …
As part of our additive componentry line, we offer Zinc Dithiophosphate 7. RB ZD 7 is a zinc dialkyldithiophosphate lubricating oil additive. It is generally used with detergent‐dispersant and acid neutralizing additives in engine oils. This additive provides oxidation, copper‐lead bearing corrosion and wear control in diesel and gasoline ...

History & Significance Zinc bis[O,O-bis(2-ethylhexyl)] dithiophosphate is a typical ZDDP molecule that would be added to motor oil for wear protection of sliding metal parts. This lot of material has been used in our laboratory for friction and wear studies on model systems using various tribological testing machines.
Smith et al. [32] observed patches having Zn, Fe and S where P was not detected and discerned the existence of Zn, S and oxygen signals below phosphorous signal in XPS depth spectra [32].Thus they suggested presence of a dense iron/zinc sulphide/oxide on the steel substrate as a distinct layer under phosphate layer (see Fig. …
A wide variety of alcohols can be employed, which allows the lipophilicity of the final zinc product to be fine tuned. The resulting dithiophosphate is then neutralized by adding zinc oxide: P 2 S 5 + 4 ROH → 2 (RO) 2 PS 2 H + H 2 S 2 (RO) 2 PS 2 H + ZnO → Zn[(S 2 P(OR) 2] 2 + H 2 O Structural chemistry. In Zn[(S 2 P(OR) 2] 2, the zinc has ...
Zinc dialkyl dithiophosphate (ZDDP) as a well-known anti-wear additive enhances the performance of the lubricant beyond its wear-protection action, through its anti-oxidant and Extreme Pressure (EP) functionality. ...
