... dithiocarbamate (MoDTC) and revealed the tribological mechanism of synergistic effect between MoDTC and P-containing additives in aluminum-based grease by combining with ZDDP and P-containing and S-free additives. Findings The MoDTC the authors prepared has good friction-reducing and anti-wear properties...

...Gabi N. Nehme; Najat G. Nehme Purpose The purpose of variable loading conditions (392 N-785N-392N-785N) with break-in period were used to study interactions between zinc dialkyl dithiophosphate (ZDDP) 0.1 P% (phosphorus) and fine-grade molybdenum disulfide (MoS₂) 3%, in different...

... formation due to tribo-chemical interactions between additives and surfaces. Design/methodology/approach In this study, four different greases were produced on the basis of a mineral base oil by varying the thickener and the addition of ZDDP. Various grease-lubricated rolling bearing experiments were...

...Penghao Qi; Shijian Wang; Jing Li; Yue Li; Guangneng Dong Purpose The purpose of this study is to reduce the use of Zinc dialkyl dithiophosphates (ZDDP) and improve the frictional properties and thermal oxidation stability of Perfluoropolyether (PFPE) grease by adding antioxidant additives...

...Wani Khalid Shafi; M.S. Charoo Purpose The paper aims to investigate the effect of zinc dialkyldithiophosphate (ZDDP) on wear and extreme pressure (EP) capabilities of hazelnut oil. Design/methodology/approach A four-ball tribometer is used to study the effect of ZDDP on the antiwear (AW...

...Chia-Jui Hsu; Jenifer Barrirero; Rolf Merz; Andreas Stratmann; Hisham Aboulfadl; Georg Jacobs; Michael Kopnarski; Frank Mücklich; Carsten Gachot Purpose To decrease wear and friction, zinc dialkyldithiophosphate (ZDDP) has been used in engine oil for several decades, but the mechanism...

...Gitesh Kumar; Hem Chander Garg; Ajay Gijawara Purpose This paper aims to report the friction and wear characteristics of refined soybean oil (RSBO) blended with copper oxide (CuO) nanoparticles and zinc dialkyldithiophosphate (ZDDP) as additives. Design/methodology/approach Four different...

...Anil P.M.; Vasudevan Rajamohan Purpose Surface roughness has been proved to be influencing the running-in wear of machined components under dry and lubricated sliding conditions. Zinc dialkyl dithiophosphate (ZDDP) is widely used as an anti-wear additive, which reduces the wear by the formation...

...Gabi N Nehme; Saeed Ghalambor Purpose – This study aims to examine the effect of the antiwear resistance of plain zinc-dialkyldithiophosphate (ZDDP) oil in the presence of Titanium-fluoride/iron-fluoride/polytetrafluoroethylene (TiF₃/FeF₃/PTFE) in the time to tribofilm...

...Martin Greaves; Ksenija Topolovec Miklozic Purpose – The purpose of this paper was to examine the film-forming behaviour of simple compositions of polyalphaolefin (PAO) containing an oil-soluble polyalkylene glycol (OSP) alone, a zinc dialkyl dithiophosphate (ZDDP) alone and then combinations...
