Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CORROSION -- FLUORIDE MELTS Аннотация: The results of tests of the compatibility of nickel-based alloys and metal-fluoride melts are generalized for molten-salt reactors.??The structure and strength characteristics of the alloys Kh80MTYu,KhN80M-VI,and MONIKR in the initial state,after thermomechanical treatment and quenching,exposure for 1200 h to thermal convection loop filled with 58NaFn15LiFn27BeF with heating by 100 C,are investigated. A method for removing 2 impurities from the melt has been developed.??The results of corrosion tests performed on samples of nickel-based alloys in a setup with natural circulation with maximum melt temperature up to 700?C and redox potential of the system 1.25n1.33 V relative to a beryllium comparison electrode are presented. It is shown that deep removal of oxidizing impurities from the melt and maintaining a low redox potential give slow uniform corrosion (less than 5µm/yr) of Kh80MTYu and KhN80M-VI samples. After the tests were completed,none of the alloys studied exhibited any tendency toward intercrystallite absorption. |
