摘要: Alloy 22, a nickel base Ni-22Cr-13Mo-3W alloy has an excellent corrosion resistance in oxidizing and reducing environments. Most of the studies on 22 have been conducted using conventional chemical or electrochemical methods. In present investigation, specimen was directly heated instead heating electrolyte, thereby simulating nuclear waste package container temperature profile. Corrosion behavior evaporation conditions water diffusing were evaluated newly devised electrode test (HECT) method simulated acidified (SAW) concentrated (SCW) this method, concentration environment varied with duration. The rate not affected by continuous increase ionic strength SAW (pH 3) environment. Passivation kinetics faster electrolytes. major difference between HECT aging characteristics passive film 22. can be used for evaluating materials construction heat transfer equipments such as evaporators.
