Abstract：

The　microstructures　of　the　Fe-based　alloy　laser　cladding　layer　were　characterized　by　optical　microscope,　scan-ning　electron　microscope　and　X-ray　diffractometer.　The　load-bearing　performance　was　evaluated　and　compared　with　that　of　the　U75V　rail.　3D　finite　element　modelling　was　performed　using　the　ANSYS　software.　It　is　found　that　the　phases　of　the　coating　are　alpha-Fe,　Fe-Cr,　Ni-Cr-Fe　and　Fe2B,　Fe3Si　precipitates.　The　average　microhardness　of　the　coating　can　reach　HV455.2,　which　is　higher　than　that　of　the　heat　affected　zone　(HAZ)　and　the　substrate.　The　coating　can　effectively　reduce　the　wear　and　rolling　contact　fatigue　of　heavy-haul　rail.
