We report a new organics cladding pretreatment technique to fabricate the austenitic steel coating via the laser remanufacturing technology and demonstrate that the organics cladding pretreatment could refine the grains and alleviate defects of the coating remarkably, which consequently enhances significantly the mechanical property. In addition, a new synchronous lateral powder feeding device is employed to prevent the nozzle from being blocked by organics coated powder and also protect the surface of the molten pool from being oxidized. This new organics cladding pretreatment technique may b...
