Paper Title:
Microstructure and Properties of La-Doped Ag-SnO2/Cu Contact Material
  Abstract

The undoped and La-doped nanostructured Ag-SnO2 coatings on pure copper substrate were prepared by supersonic plasma spraying. The phase compositions and microstructures of coatings were characterized and mechanical properties including micro-hardness and bonding strength of coatings were measured. Meanwhile, conductivity test was performed on the both Ag-SnO2/Cu contact materials. Compared with undoped Ag-SnO2 coating, La-doped Ag-SnO2 coating exhibits the more dense structure with fewer pores, and show slightly higher micro-hardness and bonding strength. Doping La can effectively enhance the electrical conductivity of Ag-SnO2/Cu contact materials.
