Abstract:
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 evaluated by four ball tester. The results show that TiDDC and TiS not only possess good antiwear and load-carrying properties, respectively, but also exhibit good antiwear synergism with BNO additive without impairing extreme pressure performances.

Abstract:
The paper presents the results of studying the lubricity of several lubricating compositions, two of which contain an antiwear additive based on a layered friction modifier - molybdenum diselenide. Oil MC-20, which does not contain functional antiwear additives, is used as a base lubricating medium and an object of comparison. Two variants for combining an antiwear additive with this oil differ in the process of initial preparation of the additive before adding it to the base lubricating oil by rotary pulsation grinding and stirring. Antiwear tests are arranged in the form of a consistent trib

Abstract:
Zinc dithiophosphate is the most commonly used antiwear additive in lubricating oil. However, zinc dithiophosphate has a poisoning effect on engine catalysis via phosphorus and zinc content that reduces the efficiency causing hazardous emission increase, therefore, it needs to be replaced with an alternative additive. In this study, the antiwear performance of molybdenum disulfide (MoS2) is enhanced by zinc sulfate (ZnSO4) addition and subjected to tribometer tests at different contact pressures to explore the MoS2 + ZnSO4friction and antiwear performance against MoS2and zinc dithiophosphate.

In this study, the tribological behavior of lamellar MoO3 as a lubricant additive was investigated under different concentrations, particle sizes, normal loads, velocity, and temperature. The friction and wear tests were performed using a tribometer and with a reciprocating motion. The results indicate that the friction-reducing ability and antiwear property of the base oil can be improved effectively with the addition of lamellar MoO3. The 0.5 wt % and 0.1 wt % concentrations of MoO3 yield the best antifriction and antiwear effects, respectively. The maximum friction and wear reduction is 19.

Even though research into aluminium-silicon alloys is becoming increasingly fashionable, very little is known regarding the tribochemistry of these substrates when lubricated with conventional engine oil additives, especially when compared against ferrous surfaces. In this thesis, many advancements and thus contributions have been made in the field of aluminium-silicon lubrication. Firstly, using a Cameron Plint TE77 tribometer, the tribological performance of overbased calcium sulfonate, zinc dialkyldithiophosphate and an organic antiwear additive on aluminium-silicon surfaces were evaluated.

Traditionally rolling contact fatigue observed in bearing field applications was subsurface initiated. However, despite an improvement in the properties of steel, some factors such as downsizing in bearing design, extreme loading of bearings as well as demanding application conditions (start-stop cycles) have led to an increase in cases of surface damage related to surface initiated fatigue, which essentially comes from surface distress. Possible causes leading to surface initiated fatigue are: material and surface properties, marginal lubrication and lubricant chemical composition. Lubricants

Abstract:
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. The key benefit of ZDPs is that they do not contain sulphur which may damage some catalysts in after-treatment exhaust systems. Utilizing ZDPs instead of ZDDPs contributes to decrease in sulphur content in engine oils. In addition, ZDP-formulated oils show better base number retention than ZDDPs, which could contribute to prolongation of engine oil life. This is
