Abstract
DC magnetron sputtering was applied in the deposition of the electrodes of the BaTiO3-based PTC ceramics. Multi-layered films of Ti/Ni-Cu/Ag and Al/Ni-Cu/Ag were prepared as the electrodes of PTCR ceramics. Experimental results indicated that there could form good ohmic contacts between BaTiO3-based PTC ceramics and the electrode materials. Also, the electrodes had good adhesion to the substrates and high-temperature welding characteristics. The proposed method has such advantages as economic consumption of production cost and controllable process, thus is suitable for large-scale industrial production.
