Erbium Oxide Sol-gel Coating as Potential Tritium Permeation Barrier and MHD Insulator
Er<,2>O<,3> coating is formed on austenitic stainless steel 316ss by sol-gel method. The results showed good crystallization of coating by baking in high purity flowing argon at 973K, and indicated that a little oxygen in baking atmosphere is necessary to crystallization of coating. The deuterium permeability of coated 316ss is about 1-2 orders of magnitude lower than that of bare 316ss, and is about 2-3 orders of magnitude than the referred data of bare F82H martensitic steel. The Er<,2>O<,3> coated 316ss have resistivity about 5 orders of magnitude higher than a minimum requirement.
