Irradiation makes structural materials of nuclear reactors degraded and failed. However, the damage process of mate-rials induced by irradiation is not fully elucidated, mostly because the charged particles only bombarded the surface of the materials (within a few microns). In this work, we investigated the effects of surface irradiation on the indirect irradiation region of the (Al0.3Cr0.2Fe0.2Ni0.3)3O4 high entropy oxide (HEO) films in detail by plasma surface interaction. The resultsshow that the damage induced by surface irradiation significantly extends to the indirect irradiation region of HEO film where the helium bubbles, dislocations, phase transformation, and the nickel oxide segregation were observed.
