“…In the work of B.A. Potekhin et al [ 20 ], various casting methods were used, including the “turbulent” casting method developed by the authors of the cited work, which made it possible to obtain a tin bearing alloy with the most beneficial microstructure with globular precipitates of intermetallic phases and the most favorable tribological properties. To improve the tribological properties of the material, H. Zhang et al [ 21 ] used surface texturing.…”

In the study, the friction stir processing (FSP) method was used to modify the surface layer of a tin-based bearing alloy. The modification was aimed at extending the service life of bearings by improving their tribological properties. The results of investigations of the microstructure, hardness and tribological properties of the SnSbCu bearing alloy after FSP using various rotational speeds of the tool—280, 355, 450 and 560 RPM—and the constant traverse speed of 355 mm/min are presented. Particular attention was paid to the possibility of changing the morphology of the precipitates present in the alloy, and to the impact of this parameter on improvement of the tribological properties. The research carried out in this paper covered investigations of the microstructure using light and scanning electron microscopy (SEM) along with analysis of the chemical composition in micro-areas and Brinell hardness tests. Additionally, the sizes of the SnSb and CuSn precipitates present in the microstructure before and after the modification process were determined, as were the tribological properties under technically dry friction conditions and lubrication with TU 32 oil. It was proven that using friction stir processing favors refinement of the microstructure and improves the tribological properties of the analyzed alloy.

“…Use of lead-based bearing materials is decreased due to legislation, health, and environmental concerns. So, Tin based materials are replacing lead bearings in recent years (Potekhin et al, 2009). Tin Babbitt is an alloy of 4-8.5% copper and 5-8.5% antimony, tin(remaining) and lead, iron, arsenic, bismuth, zinc, aluminum, cadmium in very small proportions (ASTM 2014).…”

In the past few years, the need for low-cost, high-performance materials is increasing. Design engineers and researchers are replacing the metals and alloys with advanced materials. Journal bearings are integral parts of machines, engines running to serve the purpose. They play a significant vital role in the performance, efficiency, minimizing the cost of operation, enhancing the durability and reliability of the system. Materials used for these moving elements have undergone tremendous change since the invention of Tin Babbitt. In this paper, a critical review of Journal bearing materials, right from the old-age Babbitt to advanced materials in use till date is presented. Metallurgical aspects and mechanical behavior of successful, widely used bearing materials along with their micro and nanocomposite alternatives are discussed. Tin Babbitt is an ideal material for journal bearing applications. So, it is taken as reference for comparing the quality of other bearing materials.
