Friction and Wear Characteristics of Molybdenum Dithiocarbamate with Alloy Steels

Tribology Online, 2006
The effects of composition of alloy steel on the friction and wear characteristics of molybdenum dithiocarbamate MoDTC were studied in reciprocated sliding contact using a ball-on-plate type tester. The oil used was squalane of a pure hydrocarbon.

Film Forming and Friction Properties of Sulphur-Free Antiwear Additives Zinc Dialkylphosphates (ZDPs) [PDF]

, 2011
ZDPs (zinc dialkylphosphates) are sulphur-free analogues of the conventional antiwear additives ZDDPs (zinc dialkyldithiophosphates). Recently, the application of ZDPs in practical use has been investigated as an alternative of ZDDPs.
