| 英文摘要 | The processing and corresponding mechanisms of the surface modification of 316L stainless steel by high current pulsed electron beam (HCPEB) were studied in detail. The results showed that MnS inclusions in the 316L stainless steel served as the nucleation sites for craters formed during the bombardment. The overheating of these inclusions or their interfaces and following eruptions are believed to be the reason for the formation of craters. MnS inclusions in the surface layer decreased with increasing the number of pulses, thus leading to a selective surface purification of the material. Moreover, the physical damages induced by the electron beam bombardment are repaired after repeated pulses, that is, the crater density decreases with increasing the number of bombardments, meanwhile, the holes in the crater centers are removed gradually. |
