ELECTRODEPOSITION OF Te-Bi-Pb TERNARY ALLOYS FOR THERMOELECTRIC ENERGY CONVERSION
Nicholas Michael Meyer, Yong X. Gan and Lusheng Su
Abstract:
In this work, electrochemical dealloying zinc from C26000 brass (Cu70Zn30 alloy) to form porous copper followed by electrodeposition of Te-Bi-Pb on the porous substrate was performed. The deposition of Te-Bi-Pb alloys was under nonequilibrium condition with linearly increasing cathode potentials. It is found that Te has the highest tendency to deposit on the substrate, while Bi and Pb have the same tendency. Scanning electron microscopic analysis indicates that with the increasing in the thickness of the Te-Bi-Pb coating, the morphology of the alloys changes from particulate into dendrite fractals. The composition of the alloys also changes from Te2BiPb to Te3BiPb. Preliminary tests on thermoelectricity of the deposited alloys on porous copper were also conducted. The results show that the Te-Bi-Pb is n-typed semiconductor. Due to the deposition of Te-Bi-Pb alloys on the copper surface, increase in the absolute value of the Seebeck coefficient was found.
Keywords and phrases:
alloys, coating, thermoelectricity, electrochemical method, nanoporous materials.
