铝锡合金摩擦磨损性能的研究

Study on Wear-Friction Properties of Al-Sn Bearing Alloys

研究了含锡量3%～30%铝锡合金的摩擦磨损性能,结果表明:随着含锡量的增加,铝锡合金的承载能力下降,摩擦系数下降。该合金的显微组织为硬的铝锡固溶体基体上分布着软的锡相质点。常温下含锡量在9%时,合金具有优良的耐磨减摩的综合性能。

The effect of Sn addition of 3%～30% on wear-friction properties of Al-Sn bearing alloys is studied in this paper. It is shown that the friction coefficient of Al-Sn tends to decrease and the bearing capacity of alloys reduces with the increasing content of Sn.The microstructure of the aluminum base alloys is the soft Sn phase particles distributing on the hard matrix(Al-Sn solid solution).The aluminum alloys with 9% Sn content has the best wear-friction properties at room temperature.
