Abstract The effects of debris particles in fretting contacts are substantial and are believed to play a key role in the difference in wear rates observed between fretting and full sliding wear. Studies of debris have shown that the effects can have detrimental or palliative effects on the parent surfaces. This work aims to explore this phenomenon through the study of fretting contacts of EN24-T (steel) and Ti–6Al–4V (titanium alloy). All combination pairs of these materials were tested in oxidative and non-oxidative atmospheres. Methods were developed to measure the wear rates throughout each test and corresponding ‘time stamped’ debris samples were analysed. Vast differences were observed in the effects of oxygen on the wear rates of the two materials. Evidence suggests that the reason for this difference is the size of the particles in the contacts, not their hardness.

碎屑类型及其对微动磨损率影响的探索

摘要 碎屑颗粒在微动接触中的影响是巨大的，并且被认为在微动磨损和完全滑动磨损之间观察到的磨损率差异中起关键作用。对碎片的研究表明，这些影响可能对母体表面产生不利或缓和的影响。这项工作旨在通过研究 EN24-T（钢）和 Ti-6Al-4V（钛合金）的微动接触来探索这种现象。这些材料的所有组合对都在氧化和非氧化气氛中进行了测试。开发了测量整个测试过程中磨损率的方法，并分析了相应的“时间戳”碎片样本。在氧气对两种材料磨损率的影响方面观察到了巨大差异。
