In reality, a thermoelectric device generally operates under a much larger ΔT and with an electrical current flowing through the thermoelectric materials.
Thermoelectric materials are evaluated based on three parameters: the Seebeck coefficient, a, electrical resistivity, r and thermal conductivity, l.

With the cylindrical magnetic abrasive apparatus designed and made by the author, a series of experiments on finishing the cylindrical surfaces of nonferromagnetic materials and ferromagnetic materials are carried out.
Choosing the optimized technical parameters, , the surface roughness of ferromagnetic materials changes from Ra 0.825µm to Ra 0.045µm after the 12-minute finishing experiment; the surface roughness of nonferromagnetic materials changes from Ra 0.434µm to Ra 0.096µm after the 20-minute finishing experiment.
In this paper, we study the mechanism of MAF, put forward four self-sharpening modes of abrasive particles, make experimental investigations in finishing the cylindrical surfaces of nonferromagnetic materials and ferromagnetic materials, and discuss the influence of MAF technical parameters on finishing performance.
Experimental Results and Discussion In the experiment, the self-made cylindrical magnetic abrasive apparatus and MAC-series abrasives are adopted. 45-steel (ferromagnetic materials) and 1Cr18Ni9Ti stainless steel (nonferromagnetic materials) are chosen as experimental materials.
