摘要: Hydrogen permeation through high-temperature resistant metals can be reduced by three orders of magnitude at 800 /sup 0/C means protective layers several ..mu..m thickness produced controlled preoxidation. The coating conditions must adjusted individually to the various alloys. With alloys under investigation, following parameters have proven successful: steam or steam/H/sub 2/, 900 1000/sup 0/C, thermocycling mode oxidation with intermediate cooling periods.
