摘要：

To apply a thermoelectric device to power generation from waste heat from a incinerator or steel factory, large size thermoelectric device or module is required. Thermal spraying is the potential candidate as a processing tool for such device because it enables to form thick layer (to 5 mm or more) with simple and short process on large plates or long pipes, which can be inserted directly within the furnace or heat exchanger. Go-doped n-type FeSi2 powder was prepared, and thermoelectric device was formed by plasma spraying with 43 kW plasma under inert atmosphere. FeSi2 layer with the thickness of 3 - 5 mm was formed on a stainless steel (SUS430) plate (100 x 100 mm) and pipe (diameter: 25mm). The properties, microstructure and performance of thermal sprayed beta-FeSi2 thermoelectric device was evaluated.
