使用自制面接触往复式滑动摩擦磨损实验机,采用质量百分比浓度为1%的硬脂酸锌水基乳化液作为润滑剂,研究了边界润滑状态下外加直流电场的几种施加方式对3种摩擦副在低速滑动时摩擦行为的影响。实验结果显示:外加电压的存在显著地改变了3种摩擦副的摩擦系数以及摩擦系数曲线的平稳程度,摩擦系数最大相对增加量和最大相对减少量分别达到200%和40%。摩擦系数的改变与外加直流电压的通断是对应的,不同摩擦副对电压接通后的响应速度和响应方式也是不同的。
Using self-made surface contact reciprocating sliding friction and wear testing machine, using 1% by weight of zinc stearate water-based emulsion as a lubricant, studied the application of several modes of application of DC electric field under boundary lubrication condition to three types of friction The influence of friction behavior when sliding at low speed. The experimental results show that the existence of external voltage significantly changes the friction coefficient and the smoothness of the friction coefficient curve. The maximum relative increase and the maximum relative decrease of the friction coefficient reach 200% and 40% respectively. The change of friction coefficient is corresponding to the on-off of applied DC voltage. The response speed and response mode of different friction pairs to voltage are also different.
