“…of composite material particle size limit based on the wear rate was increase or decrease with increase of load with increasing content of zinc component. The wear resistance of Zn-based alloy enhanced with increasing A2 content [16]. The overall wear resistance of the MMC under all control conditions can be attributed to the ceramic particles, which have the ability to restrict the deformation and to prevent hard asperities from causing abrasive wear [17].…”

In this study, we report effects of zinc on casted aluminium 7075 by using of stir casted method. The volume fraction of composites is prepared by density method. Stir casted composites are fabricated in different volume-fraction levels. Microstructure analysis of alloy and nanocomposites are performed by using SEM. Dry sliding wear is measured on pin-on-disc testing apparatus at various testing conditions for alloy and nanocomposite materials. As shown with the obtained results, the wear resistance increases with increasing the wt.% of reinforcing zinc nanoparticles. The different volume fractions of fabricated composites are shown, which leads to decreasing the wear rate from 40% to 60%. The nanoparticles' sizes, microstructure, and wear rate are approximated from high-resolution diffraction analysis.Keywords: AA7075-T6 aluminium alloy, reinforcing zinc nanoparticles, stir casting, wear rate, SEM.Дана робота стосується дослідження впливу цинку на литий алюміній 7075 при використанні методи лиття з перемішуванням. Об'ємну частку композитів підготовлено методою ущільнення. Перемішані литі компо-зити виготовлено за різних рівнів об'ємної частки допанту. Мікрострук-турну аналізу стопів і нанокомпозитів виконано за допомогою СЕМ. Зно-шування сухого ковзання для стопів і нанокомпозитних матеріялів ви-значали на штифт-диск-апараті за різних умов випробувань. Результати досліджень свідчать, що опір зношуванню зростає при збільшені мас.% Ключові слова: алюмінійовий стоп АА7075-Т6, зміцнювальні наночасти-нки цинку, лиття з перемішуванням, швидкість зношування, СЕМ.Данная работа посвящена исследованию влияния цинка на литой алюми-ний 7075 при использовании метода литья с перемешиванием. Объёмная доля композитов подготовлена методом уплотнения. Перемешанные ли-тые композиты изготовлены при различных уровнях объёмной доли до-панта. Микроструктурный анализ сплавов и нанокомпозитов выполнен с помощью СЭМ. Износ из-за сухого скольжения для сплавов и нанокомпо-зитных материалов определяли на штифт-диск-аппарате при различных условиях испытаний. Результаты исследований свидетельствуют, что со-противление износу растёт при увеличении масс.% упрочняющих нано-частиц цинка. Наблюдалась различная объёмная доля изготовленных композитов, что приводило к уменьшению коэффициента износа с 40% до 60%. Размеры наночастиц, микроструктура и скорость износа согласуют-ся с данными высокоразрешающего дифракционного анализа.Ключевые слова: алюминиевый сплав АА7075-Т6, упрочняющие наноча-стицы цинка, литьё с перемешиванием, скорость износа, СЭМ.

“…Rapoport et al (2002) and Gronostajski et al (2002) determined the friction coefficient of ~0⋅08 in bronze bearings. Türk et al (2007) determined the friction coefficient of ~0⋅25, wear rate of 25 mg/km in SAE 660 bronze bearings at 0⋅5 m/s sliding speed and 30 N loads. In these studies, they reported that the wear rate increased with increasing applied load, and decreased with increasing sliding distance.…”

Copper, aluminum and tin-lead based alloys are widely used as journal bearing materials in tribological applications. Bronze and brass are widely used as journal bearing materials for copper based alloys. Zamacs find applications as journal bearing materials for zinc based alloys, while duralumines are chosen as journal bearing materials for aluminum based alloys. In addition, white metals are widely used as journal bearing materials for tin-lead based alloys. These alloys ensure properties expected from journal bearings. In this study, tribological and mechanical properties of these journal bearings manufactured by metals were investigated. SAE 1050 steel shaft was used as counter abrader. Experiments were carried out in every 30 min for a total of 150 min by using radial journal bearing wear test rig.
