| Abstract Scope |
During last decades, many researches revealed that the large pulsed electron beam (LPEB) can effectively modify surface properties inducing a re-solidified layer. In recent researches, the high current pulsed electron beam (HCPEB) was adopted for the surface modification of Mg-alloys. However, the energy density of the previous works has been limited at low level. Thus, further investigations on the LPEB irradiation with the high energy density should be explored for the best performance of the LPEB surface treatments on Mg-alloys. In this study, we attempted to develop a selective evaporating process of Mg by the LPEB irradiation to improve the corrosion resistance and surface mechanical properties along with the phase transformation on the re-solidified layer with Al enrichment. The LPEB irradiation was carried with a high energy density range. The modified surface characteristics were evaluated in terms of microstructure, corrosion resistance, and wear resistance. |
