(Ti,Nb)C　reinforced　Fe-based　laser　coatings　were　prepared　with　normal　and　high　scanning　velocities　of　the　laser　beam.　The　distribution　characteristics　of　reinforced　particles　in　the　coatings　were　investigated.　The　mechanical　properties　of　coatings　were　tested.　The　results　showed　that　the　morphologies　of　the　microstructure　and　the　reinforced　particle　changed　dramatically　at　high　solidification　rate　due　to　rapid　laser　processing　compared　with　that　prepared　by　normal　processing.　Two　kinds　of　particles　were　observed　in　the　coating.　One　was　(Ti,Nb)C　multiple　carbide　particle　with　the　size　of　micron　and　sub-micron　scales,　in　which　a　mass　of　dislocations　were　found.　Another　was　nano-sized　particle　including　alpha-Fe　and　(Ti,Nb)C　obtained　by　rapid　solidification.　The　microstructure　of　the　coatings　was　highly　refined　and　a　large　number　of　twin　crystals　were　found　in　matrix.　The　results　of　mechanical　properties　test　revealed　that　the　wear　resistance　of　the　coating　was　improved　by　rapid　laser　processing,　compared　with　that　of　the　coating　prepared　with　normal　speeds.　The　above-mentioned　conclusion　indicated　that　rapid　laser　cladding　can　promote　not　only　the　processing　efficiency　but　also　the　mechanical　properties　of　the　coating.
