摘　　要：采用四氟化碳作为反应气体,对丁腈橡胶试样表面进行等离子体氟化改性处理,以改善橡胶表面的摩擦性能,并初步探讨表面含氟涂层的减摩机理。结果表明:橡胶表面氟化处理后沉积上了含氟物质,摩擦因数较未改性试样明显降低;处理功率对改性试样表面的摩擦性能影响较大,处理功率太大或太小都会减小试样表面的氟含量;处理功率为140W时试样磨损后表面平整,涂层与基体具有良好的相互作用,氟分布均匀,减摩效果最优。The surface of NBR was fluorinated by plasma technology and using carbon tetrafluoride as the reaction gas to improve the anti-friction performance of rubber surface,and the anti-friction mechanism of the modified surface containing fluoride was discussed.The results showed that the surface of rubber was successfully fluorinated after plasma treatment,and the friction coefficient was reduced significantly compared with that of the unmodified sample.The plasma power was the key processing parameter influencing the anti-friction performance of modified sample.Improper modification power（either higher or lower） would result in low fluorine content on the surface of the sample.When the processing power was 140 W,the modified sample surface was smooth after friction test,the adhesion between the fluorinated layer and the NBR substrate was good,the fluoride was distributed uniformly,and the anti-friction effect was the best.
