Fe-Cr-Si-P amorphous composite coatings are fabricated on 304L substrates by laser cladding. The effects of laser scanning speed on microstructure and properties of Fe-based amorphous coating are investigated. The results show that the coating mainly consists of amorphous, Fe3P and Fe2Si phases. With the increase of scanning speed, the dendrites gradually refine and the width of epitaxial growth layer decreases. When the laser scanning speed is 400 mm/min, the maximum microhardness of the coating is 821.3 HV0.2, the coefficient of friction under the load of 100 N are 0.076, and the coating shows better properties.
