Abstract:
1. A system for the high temperature in-situ determination of corrosion characteristics of a molten metal on an alloy under study comprising: a. a furnace, wherein said furnace is operated at temperatures in the range of about 450 degrees Centigrade to about 480 degrees Centigrade; b. a first crucible provided in said furnace; c. a reference electrode formed from a generally pure form of a generally pure first metal provided in said first crucible; d. an electrolyte provided in said first crucible, said electrolyte comprising a molten salt of a halide of said first metal; e. a second crucible provided within said furnace, said second crucible comprising a solid electrolyte, and wherein said second crucible is suitable for containing a molten metal under study; wherein said molten electrolyte and said solid electrolyte are each ionic conductors; f. a measuring electrode formed from an alloy under study, said measuring electrode being immersed in said second crucible; and g. means to measure exchange current density and transferred electrons by electrochemical means for determining the corrosion effect of said molten metal under study on said alloy under study.
