MoDDP dialkyldithiophosphate

Temperature effect on reduction of friction. Thermal stabilities of molybdenum dialkyldithiophosphates (MoDDP) are much lower (below 180 °C) than those of the corresponding MoDTC, 300°C. The type of ZDDP must also... 

The molybdenum dialkyldithiophosphates (MoDDP) were able to reduce friction effectively in mineral oil in the absence of other additives. The MoDTC only reduces friction to boundary values of about 0.095 however, mixtures of MoDTC and ZDDP can give much lower boundary friction coefficient values, below 0.04 (Graham and Spikes, 1999 Tripaldi et al., 1999). 

Molybdenum additives By using data from Table 5.15, determine a protective tribofilm formation from the degradation of molybdenum dialkyldithiocarbamate (MoDTC), molybdenum dialkyldithiophosphate (MoDDP) directly and in combination with ZDDPs or sulfur compounds.
