The experi-ments show that the silicon coupling agents react with the oxidates in the surface of NdFeB magnetic powders so that a good adhesiveness can be formed between epoxy resin and NdFeB powders. The results still indicate that the silk or wavy morphological structures in the fracture surface of the magnetic composite are more advantageous to its mechanical properties.展开更多
文摘By NdFeB magnetic powders treated with the silicon cou-pling agents, mechanical properties of the magnetic composite are remark-ably improved, and its magnetic properties are not affected. The experi-ments show that the silicon coupling agents react with the oxidates in the surface of NdFeB magnetic powders so that a good adhesiveness can be formed between epoxy resin and NdFeB powders. The results still indicate that the silk or wavy morphological structures in the fracture surface of the magnetic composite are more advantageous to its mechanical properties.
