Laser　cladding　is　a　new　surface　repair　method　that　can　improve　the　wear　and　corrosion　resistance　of　substrate　sur-　faces.　However,　the　cladding　layer　typically　exhibits　a　rough　surface,　high　hardness　and　large　residual　tensile　stress,　and　thus　requires　further　machining　and　finishing.　Ultrasonic　rolling　(U-rolling)　is　a　highly　efficient　finishing　and　strengthening　process　that　combines　ultrasonic　technology　with　traditional　rolling　(T-rolling).　In　this　study,　an　iron-based　alloy　was　coated　onto　the　surface　of　H13　die　steel　using　laser　cladding,　and　the　surface　of　the　cladding　layer　was　polished　using　U-rolling.　The　effects　of　U-rolling　on　the　surface　quality,　corrosion　resistance　and　friction　and　wear　properties　of　the　laser-cladding　layer　were　investigated　and　compared　with　those　obtained　by　T-rolling.　The　surface　roughness　of　the　U-rolled　sample　was　only　1/4　that　of　the　T-rolled　sample.　The　hardness　and　residual　compressive　stress　of　the　laser　cladding　layer　after　U-rolling　were　higher　than　those　after　T-rolling.　Similarly,　the　surface　corrosion　resistance　of　the　laser　cladding　layer　after　U-rolling　was　higher　than　that　after　T-rolling.　U-rolling　changed　the　surface　roughness,　grain　size,　and　residual　stress　of　the　material　and　thus　affected　the　corrosion　resistance　of　the　laser　clad-ding　layer.　The　friction　coefficient　and　wear　rate　of　the　U-rolled　surface　of　the　cladding　layer　were　lower　than　those　of　the　T-rolled　surface.　In　addition,　the　tribological　properties　of　the　cladding　layer　were　found　to　be　related　to　the　rolling　direction.　When　the　friction　direction　of　the　sample　was　the　same　as　the　rolling　direction,　its　friction　and　wear　performance　were　higher　than　those　when　the　two　directions　were　perpendicular.
