The effects of different powder compositions on the microstructure and properties of the sintered oil bearings were investigated. Three different types of powder were used for the comparative tests. The research conclusions show that three different types of raw material powders have different pore structures. In the case of mixed powders, the sintered samples have a self-lubricating function that can both store oil and supply oil to the friction surface through capillary pores. When the raw material is a mixed powder in which Cu powder is less than 75 μm, it has the best self-lubricating function and oil retention.

“…Babbitt alloy is the most widely known sliding bearing material, which has good antifriction ability, embedability, frictional conformability and anti-seizure property. It is widely used in internal combustion engines, construction machinery, turbo-machinery and generators [1][2][3][4]. Preparation methods of babbitt-steel bimetal materials include centrifugal casting [5,6], arc spraying [7], plasma-arc powder deposition [8], laser cladding deposition [9], TIG arc brazing [10], MIG arc brazing [11], etc., and each preparation method has its advantages.…”

The babbitt-steel bimetal sliding bearing material prepared by the MIG brazing has been applied in many fields. In the application, usually only the bonding force is tested, and the fatigue strength is not evaluated. For this reason, this study referred to the test method for the fatigue strength of bearing materials of internal combustion engines, used the sapphire test machine (Dana Glacier Vandervell Bearings, UK) to inspect the SnSb11Cu6 babbitt-steel bimetal material prepared by MIG brazing, and analyzed the test results in depth. The test results show that, the fatigue strength of the bimetal material is more than 40 MPa. In comparison, according to the same test method and conditions on the same sapphire test machine, the fatigue strength of the SnSb11Cu6 babbitt-steel bimetal bearing material obtained by the centrifugal casting method after optimizing process was usually around 35 MPa. Therefore, the MIG brazing could produce higher fatigue strength for SnSb11Cu6 babbitt-steel bimetal bearing material. In addition, in this study, the process of fatigue failure was usually that after the microcracks were generated on the surface, they expanded to the inside of the lining, thereby resulting in spalling. This study has guiding significance for engineering practice and scientific research.
