The Synergistic Antiwear Performances of Organic Titanium Compounds Containing Sulfur with Borate Ester Additive

open access: yesJournal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018
Two oil‐soluble organic titanium compounds (OTCs) such as titanium dialkyldithiocarbamate (TiDDC) and sulfurized titanate (TiS) were synthesized and identified by Fourier‐transform infrared spectroscopy (FTIR). The antiwear and extreme pressure properties of TiDDC or TiS with borate ester containing nitrogen (BNO) additive in mineral base oils were ...

Friction and wear phenomena of vegetable oil based lubricants with additives at severe sliding wear conditions [PDF]

open access: yes, 2017
The tribological responses of palm oil and soybean oil, combined with two commercial antiwear additives (zinc dialkyl dithiophosphate and boron compound), were investigated at a lubricant temperature of 100 °C and under severe contact conditions in a ...

Elucidating the Friction Catalytic Lubrication Mechanism of Ag Nanoparticles Loaded on MOFs

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 17, September 8, 2025.
A novel Ag@Co‐BDC nanocomposite lubricating additive is successfully synthesized, which effectively promoted interfacial tribochemical reactions to form a protective tribofilm during friction, resulting in a 16.7% reduction in friction coefficient and a 61.5% decrease in wear rate for base oil.

Influence of Antioxidant‐Enhanced Polymers in Bitumen Rheology and Bituminous Concrete Mixtures Mechanical Performance

open access: yesAdvances in Materials Science and Engineering, Volume 2015, Issue 1, 2015., 2015
This paper evaluates the effect of polymer enhancement with antioxidant in the rheological properties of bitumen and mechanical properties of bituminous concrete mixture (BCM). In this study, two antioxidant‐enhanced polymers were utilized in mitigating bitumen hardening due to aging.

Tribology of polypropylene and Li-complex greases with ZDDP and MoDTC additives [PDF]

open access: yes, 2017
The influence of thickener and additive interactions on grease lubricating performance is examined. Polypropylene and lithium complex thickened (Li-complex) greases were tested both as neat greases and with a 2 wt% addition of ZDDP and/or MoDTC.

Vulcanization Temperature Impact on Cross‐Linking Density and Compression Set of Sulfur‐Cured Ethylene–Propylene–Diene Monomer

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 29, August 5, 2025.
ABSTRACT The aim of the research was to find a fast and reliable measurement method for the prediction of functional properties such as compression set (CS) of rubber profiles. Research shows that the best method for testing network density and crosslinks structure for a finished product, such as complex car seals, is equilibrium swelling. Measurements

Surface Analysis of Chain Joint Components after Tribological Load and Usage of Antiwear Additives

open access: yesConference Papers in Science, Volume 2015, Issue 1, 2015., 2015
Wear in chain joints leads to an increased clearance and thus an elongation of the entire chain which determines the lifetime of the chain. This particularly applies for chains that are used in timing chain drives. The aim of this study was to investigate especially the influences of lubricant additives and a contamination with carbon black on the ...

The influence of zinc dialkyldithiophosphate and other lubricant additives on soot-induced wear

open access: yes, 2011
Diesel engines are becoming increasingly popular in both passenger and commercial vehicles because they offer better fuel efficiency than their gasoline counterparts.
