OSTI ID:6936245
An ion microprobe was used to investigate the failure of sheathed Pt/Pt-Rh thermocouples. The particulars of this study have been detailed in two prior literature reports. In this study, it was observed that under the reducing conditions set up in the thermocouple the Pt and Pt-Rh thermoelements act as reducing agents for the MgO or Al/sub 2/O/sub 3/ used as insulation. Metallic Mg or Al then diffused into the Pt and Pt-Rh wires.
