Corrosion and high-temperature steam oxidation of E110 alloy and its laser welds after ion irradiation

Corrosion and high-temperature steam oxidation of E110 alloy and its pulsed laser welds were investigated. An attempt to improve performance properties has been made by modifying the surface with a pulsed ion beam. The properties of welded joints that affect their resistance to corrosion and high-temperature steam oxidation are presented. The results of the study of surfaces and cross-sections of the pre- and non-irradiated samples after autoclave corrosion test of high-temperature steam oxidation are shown and discussed. It was concluded that there are no reasons to recommend the studied technology of surface modification to the nuclear industry.
