NITROGEN TETROXIDE CORROSION STUDIES OF CRYOPANEL MATERIALS FOR SPACE CHAMBER PROPULSION TESTING

Abstract

The corrosive action of nitrogen dioxide gas and nitrogen tetroxide cryodeposit on several cryopanel metals was investigated. The specimen temperatures were periodically cycled between 77 and 300K. The nitrogen dioxide gas pressure at ambient temperature was 4 torr. Three tests were made at different exposure periods. The basic metals tested were aluminum 1100, phosphorus deoxidized copper and stainless steel specimens, and an external bending stress was placed on selected specimens during the test.
