Abstract

An amorphous coating was synthesized on low carbon steel by laser cladding Co-based self-fluxed alloy powder successfully. The microstructure, thermal stability property of the fabricated amorphous coating was investigated. The thickness of amorphous coating was 400 µm while the dendrite zone was only 10 µm height near the interface. The volume fraction of amorphous was 85.1% approximately. DSC curve showed that the glass transition temperature and the crystallization temperature were 298 °C and 342 °C, respectively. The supercooling liquid region was 44 °C which ensured the high thermal stability of amorphous coating against crystallization.
