“…The heat treatment proposed by B. Leszczyńska-Madej [ 11 , 12 ] enables the refinement of and a change in the morphology of precipitates occurring in the alloy, lowering the coefficient of friction of the friction pair, thus reducing the wear rate under lubricated working conditions [ 11 ]. On the other hand, the authors of work [ 13 ], as a result of thermo-plastic treatment, obtained an anti-friction layer with a fine-grained microstructure and evenly distributed β phase precipitates (SnSb), which also contributed to a reduction in the wear intensity. According to the research presented in [ 14 ], high plastic deformation in the process of equiangular channel pressing (ECAP) leading to a reduction in grain size and strong refinement of the intermetallic phase particles (SnSb, Cu 3 Sn) causes even a fourfold reduction in the wear rate and a decrease in the coefficient of friction of the Babbitt–steel pair.…”

The article presents the results of tests of the tribological properties of a bearing alloy on a tin matrix (B89) after surface modification by means of friction stir processing (FSP) with a Whorl tool. The samples were processed using two tool speeds of 280 and 580 RPM and a constant linear speed of 355 mm/min. The obtained results proved the significant influence of FSP on both the morphology of the precipitates and the investigated properties. Changes in the nature and course of friction were also observed, including the participation of individual wear mechanisms in the studied test conditions. The use of the 560 RPM tool rotation speed reduces the friction coefficient and the weight loss by about 30%. The flexural strength was also increased from 123 to 307 MPa.

“…Large, angular precipitates of SnSb with sharp edges easily fall out of the matrix, leaving voids behind and creating deep scratches during operation of the bearing, at the same time accelerating its wear. The authors of work [7] presented the positive influence of thermoplastic processing on the Babbitt properties. As a result of applying pressure (5 MPa) in the crystallization process and then using die forging at the temperature of 210-235°C, they obtained an anti-friction layer with a fine-grained microstructure and evenly distributed β phase (SnSb) precipitates, which also contributed to reduction in the wear intensity.…”

The paper presents the results of research on the microstructure and selected mechanical properties of the SnSbCu-bearing alloy after friction stir processing (FSP). The Whorl tool was used for modification; the process was carried out using two rotational speeds of the tool: 280 and 450 RPM and a constant linear speed of 355 mm/min. Microstructure studies were performed employing the techniques of light microscopy and scanning electron microscopy along with analysis of the chemical composition of micro-areas. Additionally, the phase composition was investigated by means of the X-ray diffraction method and statistical analysis of the precipitates present in the investigated alloy. In addition, hardness, flexural strength, and uniaxial compression tests were performed before and after FSP modification. It was proved that using FSP to modify the SnSbCu alloy promotes refinement and homogenization of the microstructure, as well as improvement of the flexural strength, whereas no changes in the hardness level were found.

“…The friction coefficient of the textured Babbitt alloy was found to be lower compared to that of the non-textured Babbitt alloy. The influence of thermal deformation treatment on the wear resistance of Babbitt alloy was previously investigated [ 13 ]. It was found that the creation of a nanostructure uniformly saturated with fine dispersed inclusions considerably increased the wear resistance.…”

Friction and Wear Reduction of Eccentric Journal Bearing Made of Sn-Based Babbitt for Ore Cone Crusher

et al. 2016

An anti-friction Babbitt alloy-coated bearing made by a casting process is a journal bearing, which is used in an ore cone crusher eccentric. The main purpose of the Babbitt coated eccentric is to provide a low friction to support and guide a rotating shaft. Despite the fact that the Babbitt-coated eccentric offers a low friction coefficient and can be operated without a continuous supply of lubricant, it suffers from mining environments and short service life. In this study, an ultrasonic nanocrystalline surface modification (UNSM) technique was used to further reduce the friction coefficient, to increase the wear resistance, and to extend the service life of the Sn-based Babbitt metal. The friction and wear behavior of the Sn-based Babbitt metal was investigated using a block-on-ring tester under both dry and oil-lubricated conditions. The results of the experiments revealed that the friction and wear behavior of Sn-based Babbitt metal could be improved by the application of the UNSM technique. The friction and wear mechanisms of the specimens were explained and discussed in terms of changes in surface properties—microstructure, surface hardness, surface roughness, etc.
