Processing and temperature-dependent properties of plasma-sprayed tungsten?stainless steel composites
Original language description
Tungsten?stainless steel (W+SS) composites and functionally graded materials (FGMs) have a potential application as joining material in plasma facing components for nuclear fusion devices. Here, tungsten provides the heat-resistant plasma facing armor, while stainless steel is the main structural material. The composite or FGM can reduce the stress concentration at the interface by providing a gradual transition. In this study, W+SS composites of various compositions were produced by water-stabilized plasma spraying. With the help of in-flight particle and plume diagnostics, powder injection was optimized for each material, and the feed rates were adjusted to account for different deposition efficiencies. The composition, structure, and thermal and mechanical properties of the coatings were characterized. As these materials are expected to function at elevated temperatures, the evolution of their properties with temperature was also studied.
