Experimental Study on Friction and Wear Characteristics of Head Hardened Weld Rails Under Various Sliding Environments
경두레일 용접부의 미끄럼 환경변화에 따른 마찰 및 마멸특성 연구
Abstract
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 manufactured by thermite welding and gas pressure one has been tested rail 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.
