| Popis: | The walls of thermonuclear reactors will be bombarded by hydrogen isotopes and helium ions simultaneously. The simultaneous irradiation by various ions can be expected to give synergistic effects in blistering. We irradiated the samples of stainless steel (0Cr16Ni15Mo3Nb) simultaneously and sequentially by D + and He + ions from one ion source in the accelerator ILU-3. The current density of D + ions was approximately an order of magnitude higher than that of He + ions, as is expected in a thermonuclear reactor. The topography of samples after simultaneous irradiation differs from the topography of the samples irradiated only by D + or only by He + ions and from the topography of sequentially irradiated samples with analogous irradiation. The density of blisters increases at simultaneous irradiation at temperatures where blister formation occurs. At temperatures where flaking occurs the simultaneous irradiation increases the erosion rate. The peculiarities of blistering and flaking under simultaneous irradiation by D + and He + ions are described and discussed. |
