Abstract

Abstract:

Different AgSnO₂In₂O₃ materials and rivets were prepared by alloy internal oxidation method.Besides,the simulated electrical properties were carried out under the conditions of DC 13.5 V,25 A and resistive load.The mechanical properties and microstructure of three kinds of wires were compared and the influence mechanism on electrical properties of different AgSnO₂In₂O₃ materials was studied.It is concluded that with the increase of Sb₂O₃ content,the density,hardness and tensile strength of wires showed a gradual decreasing trend.When Sb₂O₃ content was low,the mechanism of material transfer was the main mechanism.As the increase of Sb₂O₃ content,the contact mechanism was mainly consumption.When Sb₂O₃ was 1%,the anti-welding resistance was the best.An appropriate amount of Sb₂O₃ could improve the anti-welding resistance of contact materials by increasing the brittleness of the melting bridge.

Key words: AgSnO₂In₂O₃, electrical property, burning mechanism, DC
