Description

Paper describes the effect of the alloying elements (chromium, aluminium, titanium, molybdenum, tungsten, niobium, cobalt) on sulfide corrosion (SC) resistance of nickel base heat-resisting alloys during 30 h in 75% Na2SO4+25% NaCl molten sat under 900 deg C temperature. The obtained patterns are compared with the effect of the mentioned metals on the long-term strength. SC high resistance and the adequate level of heat resistance are ensured by a certain doping of a nickel base

Abstract (Russian)

Описано влияние легирующих элементов (хрома, алюминия, титана, молибдена, вольфрама, ниобия, кобальта) на сопротивление сульфидной коррозии (СК) жаропрочных сплавов на никелевой основе за 30 ч в расплаве 75% Na2SO4+25% NaCl при температуре 900 град С. Найденные закономерности сопоставлены с влиянием тех же металлов на длительную прочность. Высокое сопротивление СК и необходимый уровень жаропрочности обеспечиваются легированием никелевой основы
