Abstract

Purpose

The purpose of this paper is to clarify the influence of low earth orbit space environment on the wear mechanism of TC4 alloy material and crank rocker mechanism.

Design/methodology/approach

In this study, friction experiments were carried out on TC4 alloy friction discs and crank rocker mechanisms, both before and after exposure to atomic oxygen and proton irradiation. Nanoindentation, grazing incidence X-ray diffraction (GIXRD), and X-ray photoelectron spectroscopy were employed to systematically characterize alterations in mechanical properties, surface phase, and chemical composition.

Findings

The results show that the wear mechanism of TC4 alloy friction disc is mainly adhesive wear in vacuum environment, while the wear mechanism of crank rocker mechanism includes not only adhesive wear but also abrasive wear. Atomic oxygen exposure leads to the formation of more oxides on the surface of TC4 alloy, which form abrasive particles during the friction process. Proton irradiation will lead to a decrease in fatigue performance and an increase in hardness on the surface of TC4 alloy, thus causing fatigue wear on the surface of TC4 alloy, and more furrows appear on the crank rocker mechanism after proton irradiation. In the three environments, the characteristics of abrasive wear of the crank rocker mechanism are more obvious than those of the TC4 alloy friction disc.

Originality/value

These results highlight the importance of understanding the subtle effects of atomic oxygen and proton irradiation on the wear behavior of TC4 alloy and provide some insights for optimizing its performance in space applications.

太空环境中基于 TC4 合金的材料表面和铰链界面的多尺度磨损机理

本文旨在阐明低地球轨道空间环境对 TC4 合金材料和曲柄摇杆机构磨损机理的影响。在这项研究中，对暴露于原子氧和质子辐照前后的 TC4 合金摩擦片和曲柄摇杆机构进行了摩擦实验。研究结果表明，在真空环境中，TC4 合金摩擦片的磨损机理主要是粘着磨损，而曲柄摇杆机构的磨损机理不仅包括粘着磨损，还包括磨料磨损。原子氧暴露会导致 TC4 合金表面形成更多氧化物，在摩擦过程中形成磨粒。质子辐照会导致 TC4 合金表面的疲劳性能下降，硬度上升，从而引起 TC4 合金表面的疲劳磨损，质子辐照后曲柄摇杆机构上会出现更多的沟纹。在这三种环境下，曲柄摇杆机构的磨料磨损特征比 TC4 合金摩擦盘的磨料磨损特征更明显。原创性/价值这些结果突出了了解原子氧和质子辐照对 TC4 合金磨损行为的微妙影响的重要性，并为优化其在太空应用中的性能提供了一些启示。同行评审本文的同行评审历史可在以下网址查阅：https://publons.com/publon/10.1108/ILT-02-2024-0051/。
