Description

technical field [0001] The invention belongs to the technical field of babbitt alloy materials, and in particular relates to a high-antimony tin-based babbitt alloy material and a preparation method thereof. Background technique [0002] Tin-based bearing alloy is a kind of Babbitt alloy. Due to its low casting temperature, relatively simple processing technology and excellent surface properties of the alloy, it is widely used in compressors, generators, motors, ball mills, gearboxes, and the motor industry, Production of bearing bushes in construction machinery industry. At present, the most widely used tin-based Babbitt alloys are ZChSnSb8-4 and ZChSnSb11-6, which are mostly used for centrifugal casting of bearing bushes. However, the traditional casting process equipment is complicated, the production line is long, the operation is cumbersome, the labor intensity is high, and the loss is high; at the same time, casting defects such as blisters, pores and cracks inevitabl...
