“…The non-stable processes in the operation of friction nodes in automotive equipment in the presence of motor lubricants were considered in papers [6][7][8][9]. The experimental studies have established the effect of various additives to oils on the stabilization of friction forces and reducing the wear of rubbing surfaces.…”

The physical mechanisms have been investigated that form and transform the corpuscular-vortex-wave thermal complexes of disturbances in contact tribosystems based on the quantum-mechanical exchange interaction. The presence of a contact gap determines the generation of pairs of quasi-particles-disturbances stabilized by wavelength and frequency. Internal instability and collapse processes in such a system of disturbances lead to the formation of defects in a tribopair's material and underlie the emergency friction regimes. This paper gives specific technical examples of the generation of thermal complexes at fretting, during the friction of sliding and rolling, and at cutting. It has been established that the destructive nature of the process of fretting at low values of reverse sliding speeds is caused by the generation and collapse of the corpuscular-vortex-wave thermal complexes. An example of acoustic friction emission in the ultrasonic region of the spectrum has been used to show the quantum nature of the disturbances generated by friction. The high-frequency spectrum of acoustic emission corresponds to the unbalanced composition of the disturbances and leads to the formation of wear particles. The exchange interaction in a tribosystem involving rolling on the plane has been considered. The results of statistical analysis of such rolling showed the existence of the effect of negative friction caused by the quantum generation of longwave disturbances. It has been demonstrated that the collapsed component of the generation of disturbances is significantly increased under the modes of materials destruction, including when cutting the materials. The corpuscular-vortex-wave mechanism of selective transfer and hydrogen wear in tribosystems has been described. It is shown that the properties of a servovite film under the mode of selective transfer are provided by the collapse processes in the system of disturbances. Similar processes at the vortex-wave transfer of hydrogen atoms in metals lead to the wear and destruction of the surface layer of friction

“…The use of polymeric composites makes it possible to improve the wear resistance of working surfaces. Based on experimental research, authors of [14] constructed the model for predicting the mechanical behavior and reaction to damage in flat samples of composite materials. At the same time, the authors found no regularities in the influence of normal and tangential stresses on the wear of composite materials and their coatings.…”

“…This ensures the necessary level of reliability. Various tests for researching and specifying the characteristics of tribojunction during liquid friction and viscous resistance were developed [4]. These tests are required for theoretical description of the friction process in the contact area in the presence of oil medium and description of the processes of interaction of oil with the working surface of parts.…”

З розвитком дисперсних систем в трибологiї створилась можливiсть ефективно використовувати функцiональнi добавки до мастильних матерiалiв у виглядi геомодифiкаторiв. При впровадженнi композицiйних олив з геомодифiкаторами не потрiбно виконувати конструктивнi змiни спряжень деталей машин, але їх зносостiйкiсть i припрацьовуванiсть збiльшується. Це потребує проведення експериментальних трибологiчних дослiджень. Запропоновано використання геомодифiкатора KGМF-1+олеїнової кислоди в якостi функцiональної добавки до моторної оливи, а для порiвняння обрано свiжу оливу Monnol TS-5 UHPD 10W40 та композицiйну оливу Monnol TS-5 UHPD 10W40+XADO HighWay for Diesel Truck (2,0...2,3 %). Зменшення моменту сили тертя рiзних спряжень зразкiв в дослiджуваних оливах фiксували на машинi тертя моделi 2070 СМТ-1 з додатковим модулем "кiльце-кiльце". Визначення iнтенсивностi зношування зразкiв в дослiджуваних оливах проводили методом вимiрювання амплiтуди акустичного сигналу безпосередньо iз зони тертя за допомогою приладу фiрми Brüel&Kjear. Виявлено, що зростання ефективностi мастильних композицiй спостерiгається у наступному порядку: Monnol TS-5 UHPD 10W4, Monnol TS-5 UHPD 10W40, Monnol TS-5 UHPD 10W40+XADO HighWay for Diesel Truck, Monnol TS-5 UHPD 10W4+KGМF-1+олеїнова кислота. Показник зносу металевих зразкiв, в середовищi модифiкованої оливи Monnol TS-5 UHPD 10W4+KGМF-1+олеїнова кислота, у порiвняннi з базової оливою зменшився на 11,5...14,3 %. Значення критичного навантаження збiльшилось на 17,2 %, а навантаження зварювання збiльшилось на 19,3 %. вiдповiдно. В свою чергу, зафiксовано, що максимальна iнтенсивнiсть зношування зразкiв при використаннi модифiкованої оливи Monnol TS-5 UHPD 10W4+KGМF-1+олеїнова кислота зменшилась в 3,4...6,0 рази.. Отриманi данi необхiднi для формування композицiйних олив та обґрунтування умов їх подальшої експлуатацiї в перiод форсованого припрацювання трибоспряжень деталей Ключовi слова: трибоспряження зразкiв, геомодифiкатор, композицiйна олива, момент тертя, зносостiйкiсть, акустична емiсiя, зона тертя, присадка, бронза, сiрий чавун
