摘要

本研究通过高温烧结在100Cr6轴承钢球表面涂覆MoS 2涂层，并对改性摩擦副进行了测试和评价。与未改性的摩擦副相比，MoS 2涂层处理显著提高了摩擦副的自润滑性能，摩擦副的摩擦系数降低了0.05，最大磨损深度降低了32%，PTFE转移膜在摩擦界面的停留时间延长。改性后，摩擦副的磨损机理由磨粒磨损转变为疲劳磨损，再转变为轻微的黏着磨损。结果表明，mos2涂层在提高球面滑动轴承的摩擦学性能和运行可靠性方面具有广阔的应用前景。

Influence of MoS₂ coating treatment on the damage behaviour of the self-lubricating friction pair of spherical plain bearings

This study applied a MoS 2 coating layer on the surface of 100Cr6 bearing steel balls through high-temperature sintering and tested and evaluated the modified friction pair. Compared to the unmodified friction pair, the MoS 2 coating treatment significantly improved the self-lubricating property of the friction pair, reduced the friction coefficient of the friction pair by 0.05, maximum wear depth was reduced by 32% during the test cycle and prolonged the retention time of the PTFE transfer film at the friction interface. After modification, the wear mechanism of the friction pair changed from abrasive wear to fatigue wear and then to slight adhesive wear. Results indicate that MoS 2 coating has great application prospects in improving the tribological properties and operational reliability of spherical plain bearings.

期刊介绍： The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there."
