(a, b) Simple thermoelectric elements sprayed onto a 228 × 25.4 mm ferritic steel plate. (a) The first layer of Ni electrodes deposited on a yttria-stabilized zirconia insulative layer. (b) The subsequent layers of Al2O3 and TiO2 sprayed atop the Ni deposits. (c, d) show the more complex star-configuration thermoelectric generator formed entirely by Air Plasma Spray.
