Long Xin is an Associate Professor in the National Center for Materials Service Safety at the University of Science and Technology Beijing. His research areas include fretting wear, fretting corrosion, crevice corrosion, flow accelerated corrosion (FAC), the mechanical or functional behavior of alloys at all length scales down to nanostructures, and surface nanocrystallization for enhancing the resistance of wear and corrosion.
Project 1 : Beijing Natural Science Foundation (2232079), total fund 200000 RMB, 2023-2025.
1. Comparative study on fretting wear mechanism of alloy 690TT tube in high temperature pressurized water under different motions: impact, sliding, and impact-sliding were carried out. The running trajectory characteristics, coefficient of friction and wear volume, induced by fretting wear under different motions were analyzed.
2. The fretting wear behavior and wear models of TA15 alloys at high temperatures were studied. The fretting running characteristics, coefficient of friction and wear volume were analyzed. The wear models at different environments were established.
