The friction and wear properties of Fe-Si alloys were examined in ethanol, and it was found that the Fe-Si alloys containing Si content higher than 66.7 atomic percent exhibited low friction coefficients. It was also found that the friction coefficients of the alpha-FeSi2 alloys could be reduced by adding 5vol% graphite. According to the XPS analysis, it is considered that the low friction of the Fe-Si alloys was due to the formations of low friction gel-type compounds, which was formed by the reaction of SiO2 with ethanol, and low friction iron oxides. Besides, it was found that borochromized specimens, not siliconized specimens, exhibited low friction coefficients in ethanol.

对Fe-Si合金在乙醇中的摩擦磨损性能进行了研究，发现Si含量高于66.7原子%的Fe-Si合金表现出较低的摩擦系数。研究还发现，添加5vol%石墨可以降低α-FeSi2合金的摩擦系数。根据XPS分析，认为Fe-Si合金的低摩擦是由于SiO2与乙醇反应形成低摩擦凝胶型化合物和低摩擦氧化铁的形成所致。此外，还发现硼铬化样品而不是硅化样品在乙醇中表现出低摩擦系数。
