论文摘要
本文实验研究了有机硅油对在二烟型构型下的AZ31B/86CRMOV7接触对的摩擦学行为的影响。在升高温度至300 oC时，将商用硅油用作AZ31B的氧化抑制剂。接触对的磨损机制是通过磨损表面的SEM形态探索的。分析表明，硅油可以有效地最大程度地减少表面氧化。与干滑动相比，有机硅油可以大大降低摩擦系数和特定的磨损速率。在润滑下，当温度升高时，温度较低的磨料磨损会转移到磨损，疲劳和粘附的组合磨损。
This paper experimentally investigated the effects of silicone oil on the tribological behaviour of AZ31B/86CrMoV7 contact pair under a pin-on-disk configuration. A commercial silicone oil was used as an oxidation inhibiter for the AZ31B at elevated temperatures to 300 oC. The wear mechanism of the contact pair was explored by SEM morphologies of worn surfaces. The analysis revealed that silicone oil can effectively minimize surface oxidation. Compared with dry sliding, silicone oil can considerably lower down the friction coefficient and specific wear rate. Under lubrication, the abrasive wear at a lower temperature can transit to the combined wear of abrasion, fatigue and adhesion when the temperature rises.
