“…The permeability of coating deposited at 600 C exhibits the highest PRF values at 873e973 K. And there was an apparent drop of PRF values for the 800 C deposited coating compared with the 600 C deposited coating. It was believed that the existence of (Fe,Cr) 2 O 3 content in the natural oxide layer of stainless steel increases its hydrogen permeability of the 800 C deposited coating [17,26,27]. (Fe,Cr) 2 O 3 on ferritic/martensitic steel caused defects and degradation in the permeation barrier coating during hydrogen permeation measurement.…”

“…Analysis of the oxides on Incoloy 800 produced by 0.94 atm HO oxidation at 520, 660, and 725°C was reported recently [17]. Depth-profile metal compositions through the oxide were determined by ion microprobe analysis Oxides produced on Incoloy 800 were highly uniform and average thicknesses varied from 0.9 to 2.4 microns, thicker oxides being produced by higher steam pressures and !…”

MASTERTritium management in any system always will include containment such that tritium release rates will be less than established limits and also will be as low as practical. The well known properties of hydrogen to permeate through most materials make the complete containment of tritium an impossible task. However, tritium release rates from a given system can be minimized by two primary efforts. First is the selection of a compatible containment material which frequently also will be the structural material. This effort should include films and barriers that would be compatible with the structural • material. Second and sometimes more important, the material should have surface chemistry in the particular system that continuously impedes tritium permeation. Containment

Some of the i~portant principles of alloy oxidation are discussed, with emphasis on the formatIOn of protective Cr 2 0 J , AI 2 0 J , and Si0 2 scales on iron and nickel base alloys. The competition between internal and external oxidation is consid~red and it is sho~n how establishment of the protective layer is influenced by va~lOus. p'ar~meters, Including alloy interdiffusion coefficient, oxygen solubility and~iffUSlVltym the alloy, and the relative growth rates of the various oxides. The lmportance of the t~ansient stage of oxidation is emphasised, with particular reference to the populatwn densities of the initial nuclei of the protective oxide and~herates of gr~wth~nd c:oa~escence of these particles to develop the healing barr~erlay'er. ConslderatlOn lS glven to the effectiveness of the protective scales iñ ervlce, wah respect to transport processes and mechanical integrity. The mfluence of the minor alloying elements, manganese, titanium, aluminium, silicon molybdenum, and niobium, on oxidation of Cr 2 0 J forming alloys is discussed. ' MST/1017
