摘　　要：在销-盘摩擦磨损试验机进行船用柴油机缸套-活塞环材料配副磨合磨损试验,利用油液检测技术研究不同磨合油对其磨合过程的影响。光谱分析结果表明:当使用加入金属陶瓷添加剂的CD40润滑油磨合时,油液中磨损性元素Fe,Cu,Al和Pb的含量在30min后呈下降趋势,说明缸套-活塞摩擦副在30min后已完成磨合;当使用CD40润滑油磨合时,油液中磨损性元素Fe,Cu,Al和Pb的含量在40min后呈下降趋势,说明缸套-活塞摩擦副在40min后已完成磨合。铁谱分析亦证明了光谱分析结果。因此,在CD40润滑油中加入金属陶瓷添加剂可缩短缸套-活塞环摩擦副磨合时间。The running-in wear test for materials of cylinder liner against piston ring has been conducted by a pin-ondisc tester. The effect of different running-in on running-in process is studied by oil monitoring technology. The spectrometric analysis resuh shows that the content of wear element of Fe, Cu, Al and Pb of oil appears in decrease after 30 min when CD40 lubricant with metal-ceramic additive is used to running-in. It means that the cylinder liner-piston ring friction pair has already finished their running-in process after 30 rain. The content of wear element of Fe, Cu, Al and Pb of oil appears in decrease after 40 min when CD40 lubricant is used to running-in. It means that the cylinder liner-piston ring friction pair has already finished their running-in process after 40 min. Meanwhile, the fervographic analysis shows the same result as that of the spectrometric analysis. Therefore the running-in time of the cylinder linerpiston ring friction pair can be reduced by use of CD40 lubricant with metal-ceramic additive.
