Description

technical field [0001] The invention relates to the technical field related to wear resistance of bearing pads, specifically a kind of 60A A method for improving the performance of tin-based babbitt alloy. Background technique [0002] Babbitt alloy is widely used and has good anti-friction properties. Compared with other bearing alloys, Babbitt alloy has better embedding and compliance and better wear resistance. Tin-based babbitt usually contains 5-8wt% Cu and 4-6wt% Sb, with the balance being Sn. Its solidification structure is soft matrix a phase (Sb dissolved in Sn) with needle-like or star-like Cu6Sn5 phase (intermetallic compound) or square SnSb intermetallic compound. Under non-water-based lubrication conditions, tin-based pasteurized alloys also have good corrosion resistance. The most outstanding feature of tin-based Babbitt alloy is its short-term seizure resistance, even when there is a lack of oil lubrication, it will not form severe scratches, which is rare ...
