Abstract

The invention discloses a method for improving the performance of a tin-based Babbitt alloy by adding Ni60A. The method comprises the following steps: S1, taking a proper amount of tin-based Babbitt alloy powder, nickel-chromium-boron-silicon alloy powder Ni60A and metal TiN powder, wherein the content of the tin-based Babbitt alloy powder is 63-87%, the content of the nickel-chromium-boron-silicon alloy powder Ni60A is 5-25%, and the content of the metal TiN powder is 8-12%; and S2, adding the nickel-chromium-boron-silicon alloy powder Ni60A, the metal TiN powder and the tin-based Babbitt alloy powder into a mixing machine for mixing, fully mixing the nickel-chromium-boron-silicon alloy powder Ni60A, the metal TiN powder and the tin-based Babbitt alloy powder for 6-8 hours, and obtainingspraying powder. The mixed tin-based Babbitt alloy powder is sprayed on the surface of H62 brass, the sprayed brass is subjected to coating surface microhardness testing and wear testing, and test results show than the surface hardness and wear resistance of the tin-based Babbitt alloy are improved.

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 solid-dissolved in Sn) with acicular or star-shaped 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 ...
