摘要
本实验全面研究了Ti_(3)SiC_(2)含量对Ag-Ti_(3)SiC_(2)接触材料电弧烧蚀行为的影响;Ag-Ti_(3)SiC_(2)复合材料经10 kV电弧烧蚀被分解氧化并形成AgO,TiO_(2)和SiO_(2),在阴极表面形成突起、气孔、剥离和褶皱。随着Ti_(3)SiC_(2)含量的增加,电弧在Ag-Ti_(3)SiC_(2)复合材料烧蚀表面上分散激溅。在复合材料中加入30 vol.%的Ti_(3)SiC_(2),Ti_(3)SiC_(2)的锁住效应可以将熔融的Ag封锁,有效地降低Ag基体的飞溅现象和电弧烧蚀对接触材料的侵蚀效应。
material The influence of Ti_(3)SiC_(2)content on the arc erosion behavior of Ag-Ti3Si C2contact Ag-Ti3Si C2composite The erosion,arc was comprehensively investigated.After10k V Ag O,the SiO_(2).an decomposed and oxidized pores,by the formation folds of TiO_(2),and cathode.morphologies of protrusions,the peelings,Ti_(3)SiC_(2)content,and dispersed formed on the surface With increasing electric arc was more on the eroded gridlock of Ag-Ti_(3)SiC_(2)composites.With30vol.%of tightly,composite,the Ti_(3)SiC_(2)addition to the splashing effect of Ti_(3)SiC_(2)could lock the molten Ag of which effectively reduced the phenomenon of Ag matrix and the erosion effect arc erosion on the contact material.
