Abstract

For effective implementation of smart machine technology, there is a great demand for real-time monitoring of the wear progression of machine components. In this work, the effectiveness of assessing wear by monitoring the airborne wear particles was investigated. Sliding wear tests were performed using different combinations of stainless steel (SUS304) and alumina material pairs while monitoring the size distribution and the number of particles using a particle counter. The results showed that particles less than 2 μm in size accounted for more than 83 % of the total number of airborne particles. However, particles greater than 2 μm account for 95 % of the volume of airborne particles. Additionally, in the case of wear volume, the total wear volume, which is the sum of the plate and the ball wear volumes, should be similar to that of the total airborne particle volume. For the SUS304/SUS304 pair, the total wear volume and the total airborne particle volume were very similar. However, in the case of alumina/SUS304 and alumina/alumina, the total wear volume and total airborne particle volume were not similar, and the total wear volume was significantly higher than the total airborne particle volume. The effectiveness of the airborne particle monitoring technique depended strongly on the material pairs. This was due to the fact that particle dispersion behavior varied with respect to the wear mechanisms of the materials.

空气颗粒监测技术在评估机械部件磨损进展方面的有效性

为有效实施智能机器技术，对机器部件磨损进展的实时监测有很大的需求。在这项工作中，我们研究了通过监测空气中的磨损颗粒来评估磨损的有效性。使用不锈钢（SUS304）和氧化铝材料对的不同组合进行了滑动磨损测试，同时使用颗粒计数器监测颗粒的大小分布和数量。结果表明，尺寸小于 2 μm 的颗粒占空气传播颗粒总数的 83% 以上。然而，大于 2 μm 的颗粒占空气中颗粒体积的 95%。此外，就磨损体积而言，总磨损体积（即钢板和钢球磨损体积之和）应与空气中颗粒的总体积相近。对于 SUS304/SUS304 组合，总磨损量和总空气传播颗粒量非常接近。但是，在氧化铝/SUS304 和氧化铝/氧化铝的情况下，总磨损量和总空气传播颗粒量并不相似，总磨损量明显高于总空气传播颗粒量。空气传播颗粒监测技术的有效性在很大程度上取决于材料对。这是由于颗粒的分散行为随材料的磨损机制而变化。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
