High-Temperature Specific Contact Resistance of Iron Disilicide Soldered to Molybdenum by Field’s Metal
Source abstract
Abstract
The target of this study is to evaluate the suitability of a contact scheme designed for thermoelectric characterization of FeSi2-based materials with the combined thermoelectric measurement (CTEM) technique. A Fe0.95Co0.05Si2 sample is mounted between the CTEM sample holder blocks made of molybdenum using Field’s metal solder. The electrical contact resistance is monitored under thermal cycling up to 580 °C by an in-house built contact resistance in situ monitoring facility. After cycling, the microstructure was studied by scanning electron microscopy and energy-dispersive X-ray spectroscopy on the cross section of the contact zone. For the developed preparation process, the specific contact resistance was found suitably low up to 415 °C (<200 μΩ·cm2 which is less than 10% of the sample resistance). Above 415 °C, oxidation degrades the electrical contact irreversibly.
