| 中文摘要: |
| 研究丁腈橡胶（NBR）与氟橡胶（FPM）在环己烷与基础油（20#机油）混合液中浸泡溶胀和摩擦磨损行为。结果表明：在环己烷混合液中，随着浸泡时间的延长，NBR的质量、硬度和弹性模量变化较大，FPM的质量、硬度和弹性模量变化很小；随着混合液中环己烷比例和负荷的增大，NBR和FPM的磨损量和摩擦因数均增大，FPM的快速磨损转变点的负荷大于NBR；混合液中环己烷比例和负荷较小时，FPM的磨痕较轻；混合液中环己烷比例和负荷较大时，定子橡胶应选择性能更优的FPM，混合液中环己烷比例和负荷较小时，可以选择性价比高的NBR。 |

| Abstract：The swelling characteristics，friction and wear behaviors of nitrile-butadiene rubber（NBR）and fluoropolymer（FPM） in the mixture of of cyclohexane and base oil（20# engine oil） were studied.The results showed that，in cyclohexane mixture solution，with the increase of immersion time，the mass，hardness and modulus of elasticity of NBR changed greatly，but those properties of FPM changed little. With the increase of cyclohexane ratio in the mixture or load，the frictional wear amount and friction coefficient of NBR and FPM increased，and the load of the fast frictional wear transition point of FPM was greater than that of NBR. When the cyclohexane ratio and the load was small，the wear of FPM was very light，but NBR could be used since its cost was lower. When the cyclohexane ratio or the load became large，FPM should be selected for stator rubber due to its better performance. |
