摘要

在边界润滑和混合润滑条件下,研究了分散在发动机润滑油中的硅酸镁和氧化铝对发动机摩擦、磨损和摩擦表面特性的影响。硅酸镁和氧化铝以极低的浓度(重量体积比0.01%)分散在发动机润滑油中,因此被称为减摩化合物(FRC)。采用四球磨损试验台对含和不含FRC发动机润滑油的球的摩擦系数和磨损疤痕直径进行了评定。利用扫描电子显微镜(SEM)和能量色散x射线(EDX)分析了球的摩擦表面特性和磨损表面的元素分布。试验结果表明,含FRC的发动机润滑油增加了新球的摩擦系数,但略微降低了新球的磨损疤痕直径,而在含FRC发动机润滑油的磨损球上进行的试验表明,与不含FRC发动机润滑油的新球相比,使用FRC发动机润滑油的磨损球的摩擦系数降低了46%。对摩擦表面形貌和元素分布的研究表明,球磨损表面的微孔中存在Si和O元素,表明FRC在降低摩擦系数和抗磨性能方面的作用。这些基于FRC的发动机润滑油可用于正在使用的发动机。

Friction Reduction Capabilities of Silicate Compounds Used in an Engine Lubricant on Worn Surfaces
Effects of magnesium silicate and alumina dispersed in engine lubricant on friction, wear, and tribosurface characteristics are studied under boundary and mixed lubrication conditions. Magnesium silicate and alumina, henceforth called as friction reducing compounds (FRC), were dispersed in engine lubricant in very low concentration of 0.01% weight/volume. Four-ball wear test rig was used to assess friction coefficient and wear scar diameter of balls lubricated with and without FRC based engine lubricant. Scanning electron microscopy (SEM) equipped with Energy Dispersive X-ray (EDX) was used to analyse the tribosurface properties and elemental distributions on worn surfaces of the balls. Test results revealed that FRC based engine lubricant increases friction coefficient but marginally reduces wear scar diameter of new balls, whereas, test on the worn-out balls running on FRC based engine lubricants shows 46% reduction in friction coefficient compared to the new balls running on engine lubricants without FRC. Investigations on tribosurfaces with respect to morphology and elemental distribution showed the presence of Si and O elements in micropores of the worn surfaces of the balls, indicating role of FRC in friction coefficient reduction and antiwear properties. These FRC based engine lubricants may be used in the in-use engines.
