레일 용접부의 미끄럼 환경변화에 따른 마찰 및 마멸특성 연구
A Study on Friction and Wear Characteristics of Welded Rails Under Various Sliding Environments
초록
This paper presents friction and wear related results of thermite and gas pressure welded rails under various environmental contact conditions. A welded rail which is fabricated by thermite welding and gas pressure one has been tested over full range of test conditions in a pin-on-disk wear testing machine. The results show that the friction coefficient and wear rates of a welded rail are heavily dependent on the contact pressures and sliding environments for two welding methods such as thermite and gas pressure weldings.
