摘要

在现代火炮系统中，模块化装药的摩擦特性对火炮供弹系统的运行有重大影响。本研究在模拟火炮环境下研究了模块装药与铝合金之间的摩擦学性能。结果表明，随着温度从 50 ℃ 降到 -40 ℃，摩擦系数先增大后减小。此外，当相对速度从 100 毫米/秒增加到 2000 毫米/秒时，COF 从 0.19 增加到 0.41。扫描电镜检测和化学成分分析表明，主要的磨损形式是粘着磨损和磨料磨损。摩擦化学反应产生的三膜包括铝钛氧化物和铝氮化物，有利于边界润滑。这项工作为火炮摩擦学研究提供了理论参考。

Investigation of friction and wear characteristics between modular charge and aluminum alloy for feeding process in artillery systems

In modern artillery systems, frictional properties of modular charge significantly impact the operation of artillery feeding system. In this study, Tribology performance between modular charge and aluminum alloy were investigated under simulated environment of artillery. The result indicates that the COF initially increased and then decreases with the temperature dropped from 50 °C to −40 °C. Additionally, COF increased from 0.19 to 0.41 when relative velocity increased from 100 mm/s to 2000mm/s. SEM detection and chemical composition analysis demonstrated that the main wear forms are adhesive wear and abrasive wear. The tribofilm including aluminum titanium oxide and aluminum nitrides generated through tribochemical reaction, which are beneficial for boundary lubrication. This work provides theoretical reference for artillery tribology research.

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.
