Abstract
In this work, the tribological properties of a novel iron-based self-lubricating composite as the tribopairs of a plunger pump were systematically studied on an end-face tribometer, and the tribological mechanism was also revealed. The results show that the wear mechanism of the composite can be ascribed to adhesive wear when the sliding speed is lower than 1.5 m/s. As the sliding speed increases from 1.5 to 2.0 m/s, the wear type transforms to oxidative wear due to the increase of tribo-oxidation. In addition, the failure criteria of the tribopair composite materials are summarised. When the average coefficient of friction is greater than 0.04, or the wear rate is greater than 9.66 μm3/(N m), the tribopair fails. This offers a valuable reference for industrial application of the tribopairs made from the iron-based self-lubricating composite.
本研究在端面摩擦磨损测试仪上系统研究了新型铁基自润滑复合材料作为柱塞泵摩擦副的摩擦学特性，并揭示了其摩擦学机理。结果表明，当滑动速度低于 1.5 m/s 时，复合材料的磨损机理可归结为粘着磨损。当滑动速度从 1.5 m/s 增加到 2.0 m/s 时，由于三氧化反应的增加，磨损类型转变为氧化磨损。此外，还总结了摩擦空气复合材料的失效标准。当平均摩擦系数大于 0.04 或磨损率大于 9.66 μm3/(N m) 时，摩擦空气就会失效。这为铁基自润滑复合材料摩擦副的工业应用提供了宝贵的参考。
期刊介绍：
Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development.
Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on:
Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives.
State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces.
Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles.
Gas lubrication.
Extreme-conditions lubrication.
Green-lubrication technology and lubricants.
Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions.
Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural.
Modelling hydrodynamic and thin film lubrication.
All lubrication related aspects of nanotribology.
Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption.
Bio-lubrication, bio-lubricants and lubricated biological systems.
Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
