摘要: Detailed corrosion information on 50and 500-hr exposure tests of a number ion engine structural metals in both cesium vapor and liquid is presented The tested for included the 300 series stainless steels, Sicromo, Inconel, as well titanium vanadium alloy Tests tantalum, tungsten, possible oxygen getter were also run Important aspects impurities study are effects potential degradation ionizer most formidable problems associated with relate to measurement level Analytical methods used other alkali have not proved entirely satisfactory
