| Abstract: | High current pulsed electron beam (HCPEB) was developed for surface modification of materials in recent years. In this paper, a new equipment using HCPEB is introduced. The mechanism to produce HCPEB was discussed in detail. The electron gun can be divided into explosive electron emission (EEE), anode plasma (AP) and oriented magnetic field. After testing of this machine, experiments, with different working parameters, were carried out on aluminum samples. Results of analysis and testing show that the microstructure of surface layer changed intensively. |
