滑动轴承合金材料及其制备方法
摘要：
本发明公开了一种滑动轴承合金材料及其制备方法，该合金材料中的各组分的构成为：Sn 4.6~5.4%，Cu 53~68%，Co 0.8~2.3%，Ni 0.3~1.2%，B 0.2~0.6%，稀土金属0.1~0.5%，第一润滑物5~7%，第二润滑物1~2%，余量为Al。其制备方法：将部分Al粉、Sn粉和第二润滑物按照配比进行球磨，然后与Cu、Co、Ni和稀土金属熔炼，然后制得中间合金棒；将剩余Al粉、第一润滑物和中间合金棒同时放入炉内加热熔炼，随后开始降温，开始加入B搅拌，随后升至浇铸温度浇铸、成型。本发明具有更好的抗压强度，能提高滑动轴承的耐磨性和抗疲劳性能；工艺简单，适合于工业化生产。
摘要（英）：

The invention discloses a sliding bearing alloy material and a manufacturing method thereof. The sliding bearing alloy material comprises 4.6-5.4% of Sn, 53-68% of Cu, 0.8-2.3% of Co, 0.3-1.2% of Ni, 0.2-0.6% of B, 0.1-0.5% of rare earth metal, 5-7% of first lubricant, 1-2% of second lubricant and the balance Al. The manufacturing method of the sliding bearing alloy material includes the steps that part of Al powder, Sn powder and the second lubricant are subjected to ball grinding according to a ratio and then are subjected to smelting with Cu, Co, Ni and rare earth metal, and then an intermediate alloy bar is manufactured; and the rest of the Al powder, the first lubricant and the intermediate alloy bar are put into a furnace at the same time to be heated and smelted, then cooling begins, B begins to be added for stirring, and then the temperature is raised to the casting temperature for casting and molding. The sliding bearing alloy material has higher tensile strength, and abrasion resistance and fatigue resistance of a sliding bearing can be improved. The technology is simple and is suitable for industrial production.
