Thermoelectric Properties of Magnesium Silicide Deposited by Use of an Atmospheric Plasma Thermal Spray

Thermal spray coatings in renewable energy applications

“…But the main drawback with this is the oxidation of particles during the spraying process, which lowers the electrical conductivity of deposited layers (Fu et al, 2012). It has shown that the thermal conductivity of Mg 2 Si layers deposited by atmospheric plasma spray is considerably lower than the bulk value (Fu et al, 2014).

“…Of importance is the uniform thermal fields of cascaded plasmas that reduces variabilities in both particle temperature and plasma-particle interactions29. Plasma spray is a flexible and scalable manufacturing processing technique capable of operating in an ambient environment and allows assembly of mesoscale multilayers both as blanket deposit and patterned structures with metals (as potential conductors), ceramics (as dielectric interlayers) and functional oxides303132. In addition, the process allows for conformal deposition directly onto components potentially enabling direct fabrication of useful thermoelectric devices for exploiting applications including cooling and refrigeration33, energy harvesting from heat34, solar thermoelectric generators and radioisotope thermoelectric generators35, and sensors36.…”
