摘要	By laser multi-layer cladding using a pulsed Nd-YAG irradiation the thickness of the cladding zone Mg-based alloys (ZM2 and ZM5) can reach about 1. 0 mm. The microstructure of the substrate and the cladding zone was studied using optical microscope, scanning electron microscopy(SEM), X-ray diffractometry(XRD) and micro hardness analysis. It is observed that constituent of ZM5 alloy is delta+Mg17Al12, that of ZM2 alloy is a+MgZn+Mg9Ce. That of cladding layer ZM2 alloy(L-ZM2) is Mg+Mg2Zn11 + MgCe; while that of the cladding layer ZM5 alloy(L-ZM5) is Mg + Mg-32 (Al, Zn)(49). The hardness of the cladding area can be increased to values above HV127. Very fine uniform microstructure and the produced new phases of nanometer/sub-micrometer order were obtained. Now, many repaired Mg-based alloy components have been passed by flying test in outside field.
