Over　the　past　decade,　researchers　demonstrated　much　interest　in　laser　cladded　metal　matrix　composite　coatings　for　its　good　wear　resistance.　In　this　paper,　in-situ　NbCp　reinforced　Fe-based　wear-resistance　coatings　with　different　designed　NbC　contents　were　produced　by　laser　cladding.　The　formation　mechanism　of　NbC　particle　was　analyzed.　The　effects　of　NbC　content　on　the　microstructure　and　mechanical　properties　of　coatings　were　investigated.　It　was　revealed　that　alpha-(Fe,　Cr),　(Fe,　Cr)(7)C-3,　NbC　existed　in　all　coatings.　NbC　particles　formed　by　the　chemical　reaction　of　Nb　and　C　dissolved　in　the　molten　pool.　The　increase　of　designed　NbC　content　led　to　the　growth　of　the　porosity　amount,　and　the　increase　of　the　size　and　the　area　ratio　of　the　particle,　as　well　as　the　transformation　of　the　NbCp　morphology　from　quadrangle　to　petaloid　shape.　Moreover,　the　micro-hardness　and　the　wear　resistance　of　the　coating　were　improved　with　the　increase　of　NbC.　When　NbCp　content　was　30　wt%,　the　mechanical　properties　decreased　slightly.　Copyright　(C)　2015,　The　editorial　office　of　Journal　of　Materials　Science　&　Technology.　Published　by　Elsevier　Limited.　All　rights　reserved.
