As　an　advanced　surface　modification　technique,　laser　cladding　has　many　advantages,　such　as　excellent　performance　of　the　laser　coating,　good　bonding　between　the　coating　and　the　substrate,　more　options　in　materials,　better　flexible　manufacturing　capacity,　and　smaller　heat-affected　zone.　In　this　paper,　the　process　optimization　in　laser　cladding　and　the　composition　adjustment　of　the　iron-based　wear-　resistant　coating　were　reviewed.　The　current　problems　and　limitations　were　pointed　out　and　the　future　work　was　also　forecasted.
