| 中文摘要: |
| 采用化学镀法在平均粒径2μm的空心微珠表面包覆了均匀完整的Ni-P非晶合金镀层,并对该材料进行了电磁性能和吸波性能测试。测试结果表明:空心微珠包覆Ni-P非晶合金镀层后矫顽力达到343.08Oe,属于电磁损耗型材料;以包覆后的空心微珠粉体为吸收剂制备吸波涂层,当涂层厚度为3 mm时,在4.32GHz达到最强吸收- 20.81 dB,当涂层厚度为1.5 mm时,在8.56～ 10.08 GHz内出现了小于- 10 dB的较宽吸收。 |
| 英文摘要: |
| Nickel-phosphorus amorphous coating was deposited on the hollow microspheres with the average diameter of 2μm by means of electroless plating. The electromagnetic performance and reflectivity were measured in order to study the microwave absorbing properties of the material. The results show that the coercivity of the electrolessed nickel-phosphorus hollow microspheres reaches 343.08 Oe,and the modified hollow microspheres belong electromagnetic loss materials. Absorbing materials made of the modified hollow microspheres are prepared, the minimum reflectivity of the absorbing coating with the thickness of 3 mm reaches- 20.81 dB at 4.32 GHz;The reflectivity of the coating with the thickness of 1.5 mm is less than- 10 dB between 8.56 GHz and 10.08 GHz. |
