摘要: Hot corrosion studies of CM 247 LC alloy werecarried out in pure sodium sulfate, as well sodiumchloride and sulfate mixtures differentconcentrations at various temperatures. A crucible test was employed to study the suitability 247LC a gas turbine blade material. It observed thatbare severely corroded just 4 hr, whileit completely consumed 70 hr when tested 90% Na2SO4 +10% NaCl 900°C. The results show that chloridecontaining melt is more corrosive than sodiumsulfate. weight loss linearly related tot1/2 (time) temperature different environments studied. Thecorroded samples were characterized by EPMA, SEM, XRD,and metallographic techniques. hotcorrosion an electrochemicalphenomenon.
