Description
Authors consider that the usage of fluorine-containing freon as a coolant in the second contour of fast reactors with heavy liquid-metal coolant of BREST type allows considerably decrease pressure and rise safety. There is a possibility of decreasing stability of freon which contacts with steel with raised content of silicon, using in heat-exchange equipment of such reactors and impoverishment of steel surface by silicon owing to formation of gaseous connection of silicon with fluorine of SiF4
Abstract (Russian)
Показана принципиальная возможность формирования защитного покрытия из MgF2 на сталях ферритно-мартенситного и аустенитного классов при их контакте с жидким магнием и газообразным тетрафторидом кремния SiF4 . Изгиб образцов сталей на 135 град. C не привел к растрескиванию поверхностной пленки, что свидетельствует о пластичности и плотном сцеплении покрытия из MgF2 с поверхностью сталиAdditional details
