“…Another example illustrating the significance of a nanostructure is the layered structure of NPs of transition metal dichalcogenides, which is more suitable for reducing friction by forming a tribo-film [163,164]. Figure 4 shows the molecular structure of MoS 2 as an example of a layered crystal structure.…”

“…It is of interest to study the tribological properties of CuO NPs dual-coated with sodium oleate and alkylphenol polyoxyethylene ether [163,164]. The COF and wear scar diameter of deionized water in the presence of dual-coated CuO NPs are significantly reduced, and excellent tribological properties under a certain load are obtained at the optimum concentration of the dual-coated CuO NPs.…”

This review focuses on the effect of metal-containing nanomaterials on tribological performance in oil lubrication. The basic data on nanolubricants based on nanoparticles of metals, metal oxides, metal sulfides, nanocomposities, and rare-earth compounds are generalized. The influence of nanoparticle size, morphology, surface functionalization, and concentration on friction and wear is analyzed. The lubrication mechanisms of nanolubricants are discussed. The problems and prospects for the development of metal-containing nanomaterials as lubricant additives are considered. The bibliography includes articles published during the last five years.

“…Layered nanoparticles, such as graphite, MoS 2 , and boron nitride, maintain the characteristics of larger surface area and higher diffusivity compared with ordinary morphology particles, making flake materials as new type of lubricant additives. Further, layered silicate was considered as one of the best candidate materials because of their low cost, nontoxic, and stability properties.…”

Talc/carbon spheres (TC) composite was successfully fabricated through a simple and eco-friendly hydrothermal method. The tribology properties of the base oil were significantly improved after adding TC composites, which had been studied by a ball on disc (BOD) tribometer. The friction coefficient of oil containing 0.5-wt% TC composite (0.5 TC-Oil) was only 0.08, with a decrease of 35.3% compared with the base oil at 5 N. Moreover, severe abrasive wear between friction pairs changed into slight plastic deformation lubricated with 0.5 TC-Oil, as confirmed by scanning electron microscope (SEM). These results reflected notable synergy between self-repair performance effect of talc and ball-bearing effect of carbon spheres. The study displayed the potential lubricating performance of the TC composite in current generation oil lubricants.

“…Кроме того, при эксплуатации техники на увеличенных интервалах замены неизбежно возникает необходимость компенсации расхода масла «на угар» и (или) в результате несвоевременно обнаруженных утечек при нарушении герметичности системы смазки. Доливки свежего масла сами по себе улучшают эксплуатационные свойства работающего смазочного материала, но при этом увеличивается риск смешения смазочных материалов разного качества и попадания внешних загрязнений при некачественном обслуживании техники в рейсах, а это уже негативно сказывается на эксплуатационных свойствах моторного масла и надежности двигателя [8,9].…”

Introduction. The effective operation of cars largely depends on the state of the engines, their downtime in maintenance and repair. Since the maintenance of modern engines is often reduced to the replacement of engine oil, the increase in the duration of its work significantly reduces maintenance costs and downtime in maintenance. Long maintenance-free operation of the internal combustion engines of automotive vehicles is directly related to the state of the engine oil used in this power unit. The aim of the paper is to show the features of the equipment operation with significant intervals of the engine oils’ replacement in order to increase the efficiency of its usage. The paper presents data on the features of the equipment operation when using high-quality motor oils with extended replacement intervals.Materials and methods. The authors conducted performance tests on the basis of MercedesBenzAxor, MercedesBenzActros cars. The manufacturer provided an estimate of the performance of engine oils. The main performance characteristics of motor oils were assessed using standard methods: kinematic viscosity was measured using a Stabinger viscosimeter, the base number was determined by an automatic AT-500 titrator, the content of wear products was obtained using an ASP-coupled emission spectrophotometer.Results. As a result, the authors presented data on the dependence of the changes in the main indicators of engine oil performance while the operating time and also substantiated the requirements for the volumes of fresh engine oil to compensate losses.Discussion and conclusions. The intermediate control allows detecting faults in the internal car engines, as well as providing the most accurate prediction of the resource of the lubricant under consideration. Therefore, the increasing of the engine oil change interval allows getting a significant economic effect.
