“…With the increase of tin content, the hardness and strength of Al-Sn alloys decrease, and the load-carrying capacity also decreases. In contrast, low-tin aluminum-based bearing alloys are cost-effective, have a wide range of applications, and have certain fatigue resistance and good seizure resistance, making them very attractive in bearing materials [2][3][4][5][6]. Al and Sn are immiscible with each other, and a continuous tin-rich network structure will be formed around the Al phase during the solidification process, resulting in the weakening of the strength of the Al-matrix interface.…”

Al-Sn bearing alloys were prepared with different electromagnetic stirring (EMS) currents. Electrochemical and immersion corrosion experiments were carried out on the samples. Optical microscope, SEM, EDS, and XPS were used to characterize the samples to study the effect of stirring current on the microstructure and corrosion properties of the alloy. The results show that the structure of the sample without EMS is all dendrites. With the increase of stirring current, the number of primary phase agglomerates is less and the grain size decreases. When the stirring parameter is 60A, 20Hz, the grain size is the most round and small, and the stirring effect is the best. In the later stage of immersion, the corrosion product film formed on the surface is more dense and uniform, which can effectively block the erosion of ions in the solution. The equivalent circuit fitting calculation shows that the Rtotal value is the largest, which is 1.79×106 Ω·cm², and the corrosion resistance is the best.

“…Многочисленные вертикальные и горизонтальные разрезы фазовой диаграммы Al-Sn-Zn, приводимые в [2,3], целесообразно валидировать или же подвергнуть дополнительному экспериментальному исследованию и термодинамическому расчету. В дальнейшем потребуются пространственные модели для фазовых диаграмм керметных систем, таких, как, например, Al-Sn-Zn-Al 2 O 3 [21,22], характеризуемых высокими трибологическими свойствами и используемых в качестве анодных покрытий для антикоррозионной защиты стали.…”

Three-dimensional (3D) computer model of the Al-Sn-Zn isobaric phase diagram is presented. It is shown that the T-x-y diagram consists of 64 surfaces and 25 phase regions. Features of Al-Zn binary system phase diagram related to decomposition of aluminum solid solution and its influence on geometric structure of liquidus and solidus surfaces in the ternary system, formed by this binary system and tin, are considered. Critical analysis of the published data was carried out and errors in visualization of those fragments of the Al-Zn T-x diagram, in which phase regions are formed with the participation of new aluminum solid solutions, appeared after the decomposition of the initial solid solution, are discussed. To design this 3D model, literary data were used, and the assessment of its quality is based on isopleths and isothermal sections from the same primary sources.
