摘      要：Based on the self-developed multi-mode fretting wear tester , the paper conducted dual-motion fretting wear tests on Zr-4 alloy tubes in the fuel rod section of pressurized water reactors in the nuclear industry at different temperatures (room temperature, 300 °C) and different radial alternating loads under the condition of 90° phase difference. The experimental results show that when the phase difference is 90°, different radial loads and temperatures have a significant effect on the dual-motion fretting wear characteristics of Zr-4 alloy tubes. The alternating radial load of dual-motion fretting wear test will cause the contact area of the specimen to have different fretting operation areas. © 2024, The Authors. All rights reserved.
