摘    要:研究了锻造态和热处理态不同成分铝基轴承合金在油润滑条件下的摩擦行为,以及材料的硬度、热处理制度和锻造对材料耐磨性的影响。所用材料是Al-8.5Si-3.5Cu和Al-15Pb-3.7Cu-1.5Si-1.1Fe。在锻造过程中,应变范围为10%~20%。并对材料进行T6热处理。在销-盘式磨损试验机上对材料的摩擦性能进行测试。结果表明,锻造过程使材料的硬度得到增加;铸造应变在10%~20%的范围内对材料的摩擦磨损影响不明显。

Abstract: The tribological behaviours of aluminium-based bearing alloys with different compositions, forged and heat treated materials, were investigated in oil lubricated conditions. Tested materials were Al-8.5Si-3.5Cu and Al-15Pb-3.7Cu-1.5Si-1.1Fe. The effects of hardness, heat treatment and forging on wear behaviours of the tested materials were investigated. In forging process, 10%-20% strains were applied. Heat treatment (T6) was performed to the materials. The wear tests of all specimens were performed with a pin- on-disc wear test machine. Forging process increased hardness value of the tested materials. A forging strain of 10%-20% has no significant effect on mass loss.
