磨损、磨粒磨损和电侵蚀磨损是Cu-Ag.Zr-Ce线材电滑动磨损的主要机制。在同种实验条件下,cu.AgZr-Ce线 材的耐磨性能优于cu-Ag—zr和cu—Ag合金的耐磨性能,相同实验条件下cu.Ag合金的磨损率为cu.Ag.Zr-Ce和 cu.Agzr合金磨损率的2—4倍。 关键词:Cu-Ag-Zr-Ce合金;电滑动磨损;接触线;接触滑板 中图分类号:TG

Although these Ag-based OMO electrodes have been extensively explored due to the very low resistivity caused by the Ag interlayer and the high transmittance caused by the antireflective effect of the dielectric/metal/dielectric structure, there have been no reports on the use of mesh-patterned OMO...
