【 摘 要 】

The research compared the stability of EMF (Electromotive Force) though the same electrode testing method. Oxidation, morphology and composition of Tungsten Rhenium alloy thermocouple wire was characterized by Zeiss scanning electron microscope (EV018)and XPS (X-ray Photoelectron Spectroscopy). The results showed that a small amount of rare earth elements droping tungsten rhenium alloy Wire can keep stable at a longer period of time in high temperature oxidation environment. Through the analysis of the SEM (Scanning Electric Microscopy) and XPS (X-ray Photoelectron Spectroscopy), the oxide film dopping rare earth is much denser, as well as lower valence oxide content. In a word, the rare earth droping in the tungsten rhenium alloy wire stabilize the EMF with specific films.
