Abstract
A tungsten coating was deposited onto a graphite substrate using the atmospheric plasma spraying (APS) technique. In order to increase the adhesion strength between the metallic tungsten(W) and graphite, a molybdenum (Mo) interlayer was pre-deposited onto the graphite surface by utilizing the APS technique. Also, after deposition of a APS-W.....

Microstructure and Mechanical Properties of Continuous Welded 50N Rail
Wookjin Choi1, Min Ji Song1, Nam-Hyoung Lim2, and Soo Yeol Lee1,*
Abstract
Rails are subjected to repeated stresses due to wheel-rail contact during train service. Rails under stress conditions undergo microstructural changes, and these cause degradations of the structural integrity and lifetime of rails. In this study, three different rails (newly-manufactured rail, newly-manufactured headhardened rail, and worn (used) rail) were compared to...
