| Abstract | 采用Ag与纳米Cr颗粒（平均粒径为30nm）共电沉积制备Ag／2．4mass％Cr复合镀层后经500℃空气中氧化两步法工艺，在cu基体上制备出电触点用Ag／4．0Cr20，复合膜．结果表明，Ag／2．4Cr复合镀层发生了Cr颗粒原位内氧化．与文献报道的采用合金内氧化法制备的常用Ag／MexO，型电触点材料（如Ag／12CdO）相比，所制备Ag／4．0Cr2O3复合膜的密度和电阻率相当，硬度更高． |
| Other Abstract | A Ag/4.0 mass%Cr203 composite film was fabricated on Cu substrate for application as electric contact through a two-step process： prior fabrication of a Ag/2.4Cr composite coating through co-electrodeposition of Ag with Cr nanoparticles （mean size： 30 nm） and then oxidation at 500℃ in air. The results showed that the Cr particles in the Ag/2.4Cr composite coating were locally and diffusionlessly oxidized. Compared to the conventional Ag/MexOy type electric contacts （such as Ag/12CdO） fabricated by internal oxidation of the corresponding Ag-Me alloys （e.g., Ag-10.5Cd） reported, the Ag/4.0Cr2O3 composite film has similar density and electrical resistivity, but a higher hardness. |
