| 摘 要： | 采用拟反应注射成型法制备了含油聚双环戊二烯(PDCPD)材料.利用MMS-1G型摩擦磨损试验机考察了PDCPD材料在摩擦速率处于中高速(5～20 m/s)下的摩擦学性能.结果表明:含油PDCPD材料在中高速干摩擦下,表现出比纯PDCPD更优良的减摩耐磨性能.纯PDCPD材料的耐磨性受摩擦速率的影响相对较小,而PDCPD含油复合材料对摩擦速率更为敏感.在较低的摩擦速率下,纯PDCPD的磨损模式呈现明显的磨粒磨损;较高摩擦速率下,纯PDCPD主要为黏着磨损和微坑损伤.含油PDCPD材料具有完全不同于纯PDCPD的磨损模式,表现为轻微的表面擦伤和疲劳磨损. |

| Abstract: | Oil-impregnated polydicyclopentadiene (PDCPD) are prepared by a simulating reaction injection molding (RIM) system. The tribological properties of the composite under high sliding speed (5~20 m/s) are evaluated on a MMS-1G friction and wear tester. The results show that the incorporation of oil in PDCPD contributes to reduction on both wear rate and friction coefficient. The sliding speed has no significant influence on wear resistance of neat PDCPD while the tribological behavior of oil-impregnated PDCPD is sensitive to sliding speed. Under lower sliding speed, neat PDCPD is characterized by abrasive wear,under higher sliding speed, adhesive wear and micro-pit damage are dominated. The wear mode of oil-impregnated PDCPD is mild surface scratch and fatigue wear and completely different from that of the neat PDCPD. |
