Effects of Environmental Humidity on the Tribological Properties of Modified PTFE Three-Layer Composites

Abstract:

In this paper, the tribological properties of the modified PTFE three-layer composites in different humidities were studied. The wear mechanisms of the modified PTFE three-layer composites with and without PI were also analyzed. The test results showed that in the humidity of 15%-75%, the friction coefficients of the composites increased with the humidity increased. At the humidity of 100%, the friction coefficient reduced significantly. With the increase of humidity, the wear of the composites decreased at first and then increased. The smallest wear appeared when the humidity was 45% or 60% for with or without PI composites respectively. And the results also revealed that PI is helpful to improve the wear stability of the composites in different humidities.
