测量了在饱和碳氢化合物液体边界润滑条件下，带电粒子在金刚石针划划各种固体时的摩擦发射行为。所测试的固体是铜、铝和铁金属，陶瓷硅、氧化锆、氮化硅、氧化铝、钠钙玻璃和云母，6，6-尼龙和聚四氟乙烯的聚合物。采用正己烷、正十一烷和正十六烷的饱和碳氢化合物作为润滑油。摩擦发射是突然发生的，随着划痕的开始和倾斜，摩擦发射突然停止。带电粒子的发射强度与固体的种类密切相关，特别是与其绝缘性能密切相关，发射强度按导体、半导体、绝缘体的顺序递增。发射强度随固体硬度的增加而降低。边界润滑条件下的这些排放特性与环境条件下的干摩擦排放特性基本相同。
The triboemission behavior of charged particles was measured under boundary lubrication of saturated hydrocarbon liquids during scratching of various solids by a diamond stylus. The solids tested were the metals Cu, Al and Fe, ceramics Si, ZrO2, Si 3 N 4 , Al 2 O 3 , soda lime glass and mica, polymers of 6, 6-nylon and PTFE. Saturated hydrocarbons of n-hexane, n-undecane and n-hexadecane were used as lubricating oils. Triboemission occurred in bursts and ceased abruptly as scratching was started and slopped. The emission intensity of the charged particles depended closely on the kinds of solids, especially on their insulating properties, with an increase of emission intensity in the order of conductor < semiconductor < insulator. The emission intensity decreased as the hardness of the solids increased. These emission characteristics under the boundary lubrication condition are principally the same as in dry friction under ambient conditions.
