摘要
本文研究了石墨粉上电镀金属的工艺及电镀金属的石墨粉加入吸波材料中对微波反射率的影响。对电镀 Cu,Ni,Co 的实验表明,金属层的复盖率不低于90%。添加镀 Cu 石墨粉的多层结构吸波材料的共振吸收峰比单层结构的高,并且吸收峰略朝高频方向移动。
A new technology of electroplating graphite powder with metals wasstudied.it has been found that continuous metal coating including Cu,Ni and Co can beavailable on the powder during an intermitten stirring process by the use of a special auxil-iary cathode in conventional electrolytes.The use of plated graphite powders as an additivein microwave absorbing material was proposed to improve the attenuation characteristic byregulating the impedence and forming microwave scattering points in the absorbent.
