Abstract Microtexturing has been implemented to analyze its efficacy in improving the tribological performance of polymeric materials for potential marine applications. Textured and untextured pins were fabricated using aromatic thermosetting copolyester (ATSP) and tested against a copper alloy. Experiments were conducted under both starved and fully flooded (submerged) conditions. Constant pressure experiments were applied at a wide range of velocities (0.008–1.518 m/s) under both lubrication conditions. It was found that, microtexturing could effectively reduce the friction coefficient under both starved (up to 26%) and submerged lubrications (up to 35%), depending on the sliding velocity. Moreover, texturing reduces oxidation of the metallic countersurface by up to 50%.

在饥饿和完全淹没条件下表面微纹理对海水润滑接触的影响

摘要 微观纹理已被实施以分析其在改善聚合物材料的摩擦学性能方面的功效,以用于潜在的海洋应用。使用芳香族热固性共聚酯 (ATSP) 制造有纹理和无纹理的针脚,并针对铜合金进行测试。实验在饥饿和完全淹没(淹没)条件下进行。在两种润滑条件下,恒压实验均以较宽的速度范围 (0.008–1.518 m/s) 进行。结果表明,根据滑动速度,微观纹理可以有效地降低在饥饿(高达 26%)和浸没润滑(高达 35%)下的摩擦系数。此外,纹理可将金属反面的氧化减少多达 50%。
