The Impact

Dust particles from the air in the electrical contact caused more and more problems. To a large extent reduce the reliability of the system. In order to study the impact of these issues, we need to analyze and discuss the dust particles on contact performance of electrical contact materials. In this paper, under static conditions with 150-212μm of the silica particles analyzed and discussed, represented by the pressure difference, particle size, being suppressed will lead to a different location of the static contact resistance and analysis of particle size of the scope of what the content of easily crushed. Experimental results show that the particle size and the location of the different particles are pressed, will make a change in contact resistance, another analysis gives easily be crushed particle size range is 150-300μm.

High energy ball milling was used in order to improve dispersion of metal oxide in Ag-SnO2 electrical contact materials. The processed Ag-SnO2 (92:8) and Ag-SnO2In2O3 (87.8:9.30:2.9) powder mixtures were subsequently consolidated to bulk solid pieces by conventional powder metallurgy method. The characterization of the prepared samples included microstructural analysis by XRD and SEM, as well as measurements of physical properties such as density, hardness and electrical conductivity. The results of X-Ray analysis point to reduction of crystallite size after milling of about ten times. Microstructures of sintered Ag-SnO2 and Ag-SnO2 In2O3 materials display very fine dispersion of the oxide components in silver matrix. Somewhat higher uniformity was obtained for Ag-SnO2 In2O3 material which was illustrated by results of SEM analysis and more consistent microhardness values. The obtained values of studied physical properties were found to be in accordance with observed higher dispersion of metal oxide particles and comparable to properties of commercial electrical contact materials of this type.
