Abstract

Abstract

The AgCuOIn₂O₃SnO₂ electrical contact materials with different SnO₂ content were prepared by the reaction synthesis method combined with the plastic deformation process. Electrical contact experiments were carried out on electrical contact materials with different SnO₂ content on the JF04C contact material testing machine, and the contact resistance, welding resistance, and material transfer characteristics of the material were studied. The microscopic morphology under erosion was analyzed. The results show that the contact resistance of AgCuOIn₂O₃SnO₂ contact material is small. When the test voltage does not exceed 12 V, the contact resistance decreases slowly with the increase of the number of tests and finally tends to stabilize. When the voltage increases to 18 V, the contact resistance of each sample is equal increase, and the degree of increase varies. For samples with constant SnO₂ content, the welding force first increases and then decreases with the increase of the number of tests. The arcing energy of the material increases with the increase of the voltage, as the number of tests increases, it fluctuates in a zigzag shape. The material in the electrical contact process is mainly cathode transfer, and the loss of the material first increases and then decreases with the increase in the amount of SnO₂. The surface of the cathode/anode contacts is convex and concave, and there are molten metal solidification patterns on the surface. The material transfer is mainly carried out by melting bridge, and the electrical contact performance is best when the SnO₂ content is 0.5wt%-1.0wt%.
