| Research Abstract |
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.
