摘要

本研究旨在比较湿度对摩擦学系统工作的影响。所测摩擦磨损为外特性;因此，它们的值可能会根据摩擦结的操作参数和环境条件而有很大差异。在aTRB3摩擦计上，在相对湿度为50%±5%和90%±5%的情况下，在15 n的载荷下，在干滑动模式下进行了摩擦学试验。摩擦结由100Cr6钢制成的试样组成，反试样由100Cr6、SiC和Al2O3钢制成。用光学剖面仪检测了表面的几何结构。摩擦学测试结果表明，相对湿度为50%±5%时，线性磨损和摩擦系数在90%±5%时有所降低。本文还介绍了在16位线性PCM标准中录制的声音，并在Spectra-Plus程序中进行了分析。

EFFECT OF HUMIDITY ON TRIBOLOGICAL PROPERTIES OF SELECTED FRICTION JUNCTIONS WITH AN EVALUATION OF ACOUSTIC EMISSION

The study aimed to compare the effect of humidity on the operation of tribological systems. The tested friction and wear are external properties; therefore, their values may differ significantly depending on the operating parameters of the friction junction and environmental conditions. Tribological tests were carried out on a TRB3 tribometer in a dry sliding mode at a relative humidity of 50% ± 5% and 90% ± 5% in the ball-on-disc configuration with a load of 15 N. The friction junction consisted of a sample made of 100Cr6 steel, and three counter-samples were made of 100Cr6, SiC, and Al2O3 steel. The geometric structure of the surface was examined with an optical profiler. The tribological test results showed reduced linear wear and friction coefficient at a relative humidity of 90% ± 5% compare to its 50% ± 5%. The paper also presents the results for the sound recorded in the 16-bit linear PCM standard and analysed in a Spectra-Plus program.
