摘要：

The impact fretting wear behavior of a 690 alloy tube affected by low-impact cycling kinetic energy was investigated. The Inconel 690 alloy specimen was clamped by cantilever and simple supported beam structures for support. The interface response was affected by the clamping situation, and material wear was affected by the change in the interface response. The energy loss, contact force versus time and frequency, energy absorption, and deformation of the material (thin wall tube) during impact were analyzed. The worn surfaces and cross-sectional morphologies were observed with an optical microscope and a 2D surface profiler to analyze the impact fretting wear mechanism under the two support structures. In the two clamping structures, wear decreased when the span increased, and material wear showed a high correlation with the peak impact force and absorbed energy. The wear mechanism of the alloy 690 specimen was delamination. (C) 2017 Elsevier B.V. All rights reserved.
