摘要
采用化学镀的方法制备了表面包覆Fe-Ni—P合金的空心微珠，研究了制备方法及条件对空心玻璃微珠表面改性的影响，并对其吸波性能进行了测试。实验结果表明，空心玻璃微珠表面镀层中铁、镍的质量分数分别为30．1％和63．2％，在频率为16．80GHz处，涂层的反射衰减可达-18．20dB，且在12．5～18．00GHz频段范围内，反射衰减皆低于-10．00dB。
The cenospheres modified with Fe-Ni-P alloy were prepared via chemical plating method. The preparation route and operation conditions were investigated. The cenosphere with different content of Fe-Ni-P alloy were obtained. The modified eenosphere were used as microwave absorbent in coating and the reflection ratio of the as-prepared coating was measured. Results showed that the maximum reflection ratio of the coating was obtained when the modified cenospheres contained 30.1% Fe and 63.2% Ni on its surface. The reflection ratio reached --18.20 dB at the frequency 16.80 GHz,and was observed below --10.00 dB in the frequency range of 12.50 -18.00 GHz.
