Due to its good comprehensive mechanical properties and low cost, 45 steel has long been widely used for the manufacture of various components. However, the relatively low corrosion resistance of 45 steel has negative effect on its application and should be further improved. In this work, a Zr50Ti5Cu27Ni10Al8 metallic glass (MG) coating was successfully obtained on 45 steel by laser cladding method. The microstructure and the morphology of the MG coating were also examined. Corrosion test indicated that the glass coated 45 steel exhibited much higher corrosion resistance than that of bare 45 steel. This is due to the alloying element Zr and the structurally and chemically homogeneous structure of MG coating.
