Abstract:
... We report a nonequilibrium fabrication method of n-type CoSb₂.₈₅Te₀.₁₅ skutterudites using selective laser melting (SLM) technology. A powder of CoSb₂.₈₅Te₀.₁₅ was prepared by self-propagating high-temperature synthesis (SHS) and served as the raw material for the SLM process. The effect of SLM processing parameters such as the laser power and scanning speed on the quality of the forming CoSb₂.₈₅T ...
