摘要:
为探讨高压海水轴向柱塞泵滑靴副的减阻抗磨机理，采用数控机床在CF/PEEK试样表面加工出不同形状仿生非光滑单元体，与316L不锈钢形成配副，对其在不同法向载荷下的摩擦因数、试样温度、磨损率等进行测试，并用激光共焦显微镜及扫描电子显微镜对磨损表面进行分析。结果表明：在海水润滑条件下，光滑表面配副以磨料磨损和粘着磨损为主，摩擦因数随时间稳定在0.05~0.09，试样温升大，磨损率大；非光滑表面配副可有效存储海水和磨屑，产生动压润滑效应、降低磨料磨损，摩擦以犁沟效应为主，摩擦因数稳定在0.02~0.06，试样温升小，磨损率小；随法向载荷的增加，由粘着效应所致CF/PEEK转移加快，摩擦因数和试样温度升高，磨损率降低且下降趋势逐渐减缓。

Abstract:
To explore the innovative mechanism to reduce resistance and anti-wear for slipper pair of high pressure seawater axial piston pump, different types of bionic non-smooth units were processed on the surface of CF/PEEK specimens using CNC machine tool. The tribological performance of friction pairs with 316L stainless steel under different normal loads were studied. The results show that abrasive wear and adhesive wear are the main forms of smooth surface friction pair. The friction coefficient fluctuates with time and stabilizes at 0.05-0.09. The temperature rises and the wear rate is high. Pits or holes can store seawater and wear debris, which helps producing hydrodynamic lubrication effect and reducing abrasive wear. The main wear form of friction pair with non-smooth surface is plowing effect and the friction coefficient stabilizes at 0.02-0.06. The temperature rises and the wear rate are low. With the increase of normal load, the transfer from CF/PEEK to 316L caused by adhesive effect is accelerated, the friction coefficient and the specimen temperature rise, the wear rate drops and its downward trend gradually slows down.
