Initial stages of oxidation of metals and alloys. Progress report, March 16, 1982
Studies of the oxidation of single crystal surfaces of Be and of Fe-Ni alloys has been continued over the past year. The kinetics of oxidation of Be (0001) have been studied in detail over the temperature range 300 to 800/sup 0/K. The oxide layer, at high temperatures, is single crystal BeO epitaxially oriented on the Be substrate; below approx. 500/sup 0/K the oxide is not monocrystalline but retains some degree of texture. Results are presented for the rate of formation of Be 0 as a function of O/sub 2/ exposure. A fairly extensive set of experiments on the kinetics of formation and structure of oxides on Fe-Ni (40 to 60 at. %) single crystals has been carried out and analyzed. Some of the preliminary results were described in last year's progress report. Experiments on Ni/sub 3/Fe (100) have been initiated. An initial series of experiments on the composition of this surface as a function of temperature has been performed.
