What is Influence of Oxygen on the Carbide Formation on Tungsten about?
As a ®rst wall material in nuclear fusion devices, tungsten will interact with carbon and oxygen from the plasma. In this study, we report on the process of thermally induced carbide formation of thin carbon ®lms on polycrystalline tungsten and the in ̄uence of oxygen on this process. All investigations are performed using X-ray photoelectron spectroscopy (XPS). Carbon ®lms are supplied through electron beam evaporation of graphite. The carbidization process, monitored during increased substrate temperature, can be divided into four phases. In phase I disordered carbon converts into graphite-like carbon. In phase II signi®cant diusion and the reaction to W 2 C is observed, followed by phase III which is dominated by the presence of W 2 C and the beginning reaction to WC. Finally in phase IV only WC is present, but the total carbon amount has strongly decreased. Dierent mechanisms of oxygen in ̄uence on the carbide formation are proposed and measurements of the reaction of carbon on tungsten with intermediate oxide layers are presented in detail. A WO 2x intermediate layer completely inhibits the carbide formation, while a WO 2 layer leads to WC formation at temperatures above 1270
