摘要

本文提出了一种替代传统氟基冷锻铝润滑油的环保型材料。根据日本工业标准，在A5052铝合金表面形成了Mg-Al层状双氢氧化物（mal - ldh）膜。使用阴离子表面活性剂制备润滑油膜。分析了膜的特性，并通过环压缩试验对膜的润滑性能进行了评价。用硬脂酸钠处理的MgAl-LDH膜具有最低的库仑摩擦系数，优于用同种表面活性剂处理的氟基膜。这种方法展示了一种新的、环保的铝冷成型预处理的潜力，为传统的氟基处理提供了一种有希望的替代方案。

Frictional property of anionic-surfactant-loaded MgAl-layered double hydroxide films on aluminum alloy using a ring compression test

This paper proposes an environmentally friendly alternative to conventional fluorine-based lubricants for the cold forging of Al. A Mg-Al layered double hydroxide (MgAl-LDH) film was formed on the surface of Al alloy A5052 according to Japanese Industrial Standards. Anionic surfactants were applied to create lubricant films. The film characteristics were analyzed, and the lubrication performance was evaluated using ring compression tests. The MgAl-LDH film treated with sodium stearate exhibited the lowest Coulomb’s coefficient of friction, outperforming the fluorine-based film treated with the same surfactant. This method demonstrates the potential of a new, eco-friendly pretreatment for Al cold forming, offering a promising alternative to traditional fluorine-based treatments.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
