Abstract：Zr60Al10Ni10Cu20 BMGs coatings powder added with 1% CeO2 were clad on Q235 steel substrates by high power semiconductor laser. By comparing the coatings with the addition of CeO2 with the coating without CeO2, The effect of rare earth addition on phase structure of coatings was investigated by energy-dispersive analysis of X-rays(EDAX),X-ray diffraction(XRD).The microhardness of the coatings were measured by microhardness tester. The corrosion rate of BMGs in different concentration of HCl was measured by weight loss method. The results indicated that with the addition of CeO2,the content of amorphous phases was increased, the microhardness and corrosion resistance of the coatings were improved.
