“…Moreover, the authors proved that the rate of tin Babbitt wear depends on the wear rate of β phase particles (SnSb). Similarly, works [ 6 , 7 , 8 , 9 ] present the influence of coating application methods on the microstructure and properties of Babbits. Additionally, the positive effect of changing the morphology of SnSb precipitates on reducing the tribological wear was also presented in [ 2 , 10 , 11 , 12 ].…”

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.

“…It was observed a great increase in the specific wear rate and mass wear for the B83 babbitt at load 50 N when compared with the test results for the same alloy at 40 and 60 N. Due to its inhomogeneous distribution and greater distance between the precipitates as can be seen in the SEM image of Figure 4, the B83 babbitt has shown non-relational results for mass wear and specific wear rate when tested at different loads [38]. Because of this, its wear rate and specific wear rate increased by increasing the load from 40 to 50 N and decrease by continuing to increase the load from 50 to 60 N. Thus, the obtained results for the B83 babbitt subjected to friction with the counter disk at a load of 50 N indicate that the wear has occurred mainly in the adhesive wear region and the limited quantity of precipitates in that region were not enough to serve as reinforcing phase as in the case of the other two loads of 40 and 60 N.…”

In this study, a hybrid material is produced, and the effect of different loads varying from 40 to 60 N against an EN-31 steel counter disk on its wear behavior under dry sliding conditions at room temperature is studied. The tribological behavior is studied via the pin-on-disk method and analyzed using primary wear parameters, such as the coefficient of friction (COF), mass wear, and specific wear rate. The obtained results are compared with the results for B83 babbitt under the same wear test conditions. Microstructural observation with scanning electron microscopy (SEM) is performed along with X-ray energy dispersive spectroscopy (EDX) for chemical analysis conduction. The results from the wear experiments indicate that the hybrid material possesses a lower COF, mass wear, and specific wear rate as well as a higher wear resistance in comparison to the B83 babbitt specimen when subjected to the same test conditions. The results from the wear experiments indicate that by applying different loads of 40, 50, and 60 N, the hybrid material possesses a lower mass wear, specific wear rate, and COF specifically at a load of 40 N in comparison to the B83 babbitt specimen under the same test conditions. It was also observed that by increasing the load under dry sliding friction, the hybrid material increases its mass wear and specific wear rate.

“…O Babbitt à base de estanho é uma liga heterogênea composta por uma matriz dúctil, que é uma solução sólida de antimônio e cobre em estanho, e duas outras fases formadas por compostos intermetálicos mais duros que a matriz [6,7]. Sendo uma destas uma fase formada por grandes cubos duros de estanho e antimônio (SnSb), e a outra composta por cobre e estanho (CuSn) em formato de estrelas ou agulhas de acordo com a quantidade presente de cada um destes dois elementos químicos [7,10].…”

RESUMO O Babbitt, também conhecido como metal patente ou metal branco é uma liga macia muito utilizada em mancais de deslizamento que trabalham em contato com aço, e tem como elementos de base estanho ou chumbo, além de compostos intermetálicos formados geralmente por antimônio e cobre. O presente trabalho buscou avaliar a influência dos parâmetros rugosidade e espessura do revestimento no comportamento tribológico da liga quando em contato com o aço ABNT 1045. Foram realizados ensaios tribológicos de pino sobre disco, utilizando pinos de aço ABNT 1045 e corpos de prova de aço revestidos com Babbitt simulando o contato de um eixo sobre um mancal revestido com Babbitt. A rugosidade e a espessura do revestimento foram variadas em três níveis, com o intuito de observar o comportamento em relação ao atrito e ao desgaste com a modificação destas variáveis. Nos ensaios que utilizaram corpos de prova com as menores rugosidades dentro da faixa analisada, ocorreu um aumento de 0,05 ± 0,02 para 0,46 ± 0,06 no coeficiente de atrito quando se elevou a espessura de revestimento de 0,45 ± 0,07 mm para 1,08 ± 0,17 mm. O maior coeficiente de atrito foi observado no ensaio do corpo de prova com maior espessura de revestimento (1,08 ± 0,17 mm) e menor rugosidade (0,47 ± 0,01 mm), o maior desgaste foi registrado no ensaio com o corpo de prova de maiores espessura de revestimento e rugosidade (1,08 ± 0,17 mm e 1,29 ± 0,20 mm, respectivamente) e o menor desgaste e coeficiente de atrito foram obtidos pelo ensaio realizado no corpo de prova com menor rugosidade (0,43 ± 0,03 mm) e espessura de revestimento média (0,45 ± 0,07 mm).
