Investigation on fretting wear behavior of 690 alloy in water under various temperatures

摘要

The aim of this paper is to assess the effect of water temperature (room temperature - RT, 60 degrees C and 90 degrees C) on fretting wear behavior of 690 alloy tubes against 405 stainless steel plates, and compare it with fretting in dry condition. Due to the lubrication effect, the presence of a thin water film likely precluded the metal-metal contact, and resulted in less wear. During the fretting process, water also washed the wear particles away from the contact zone leading to a decrease of abrasive wear. Consequently, the wear scars showed "U" shape profile along the fretting direction in water, while "W" shape in air. (C) 2016 Elsevier Ltd. All rights reserved.
