AbstractTo protect CoSb3-based skutterudite thermoelectric materials from oxidation and to suppress the sublimation of antimony in long-time service, a series of surface coatings including Al, Al-Ni, Al-Ni-Al were deposited onto Yb0.3Co4Sb12 by using an electrochemical deposition method. The thermal aging behavior for the Yb0.3Co4Sb12 samples with and without different surface coatings were investigated by accelerated thermal aging tests at 873K. Thermoelectric properties of Yb0.3Co4Sb12 with different coatings after aging are used as the evaluation criteria for coating effectiveness. After thermal aging at 873K for 30days, the thermoelectric properties of Yb0.3Co4Sb12 coated with Al-Ni double-layered coating were almost undecreased, indicating that the Al-Ni coating is suitable for protecting CoSb3-based skutterudite from oxidation and for suppressing the sublimation of antimony. It is expected that this coating could improve the reliability of CoSb3-based devices and could accelerate the application of skutterudite thermoelectric generators.
