摘要：
Helium was implanted in 316L stainless steel to produce a marker layer of bubbles to provide a reference for the assessment of oxidation and dissolution during proton irradiation in 320 degrees C hydrogenated water for 24 h and 72 h. Inner oxide thickness characterized by TEM dropped by a factor of 4.5 with irradiation. Marker layer measurements reveal a factor of 3 lower metal loss with irradiation. Metal loss increased without inner oxide growth between 24 h and 72 h of irradiation. Greater enrichment of chromium in the oxide under irradiation yields a more protective oxide film despite evidence of oxide dissolution.
