Thermophysical Properties of Ag-CdO Composite Materials

Evolution of the AgCdO Contact Material Surface Microstructure with the Number of Arcs

“…Most have been based on the comparison of arc erosion behaviors and contact material properties between AgCdO and some potential candidates for different applications: AgSnO 2 , 1-13 AgSnO 2 In 2 O 3 , 5,6,14,15 AgZnO, 3,6 AgNi, 6,7,10-12 AgW, 6,10 AgCu. 7,10 A few have dealt with the x-ray study of AgCdO, 16,17 with the metallurgical study of AgCdO, 18 with the effects of additives on the microstructure and properties of AgCdO, 19 with the thermophysical properties of AgCdO, 20 and with the effect of arcing on the microstructure and morphology of AgCdO. [21][22][23][24] However, none of them has related the surface dynamics of the AgCdO contact material to its properties of good resistance to arc erosion, whereas defining what makes AgCdO a good contact material is the first and crucial step in the process of designing a good substitute.…”
