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 AbstractA 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.
