| Abstract: | The long term compatibility of both N2O4 and N2O4 + 1%NO with titanium alloy(TC4), stainless steel(304L)and welded TC4/304L was studied in this paper.First, the determination of the specimens and the assay of the media were carefully completed in the experiment, and the first-class compatibility data was obtained; Second, the anticorrosive mechanism of TC4 and 304L was initially understood through the XPS depth profiles of the corroded specimens. |
