【摘要】 本文采用高导电粒子的微观渗透来提高Ｎｉ涂层的屏蔽效能。低Ｎｉ含量（５０％ｗｔ）的Ｎｉ涂层经Ｃｕ粒子微观渗透后，屏蔽效能比高Ｎｉ含量（８５％ｗｔ）的提高２０ｄＢ左右。这是由于Ｃｕ渗透入低Ｎｉ涂层中微观孔洞网络内沉积，形成更多的锁链通道和电子隧道，增大导电网络密度，使其导电性能提高１个数量级所致。并探讨了控制Ｎｉ涂层导电性的理论。更多还原

【Abstract】 In this paper Hiconductive particles micropenetrating into Ni paint to increase its shielding effectiveness (SE) was studied. SE of low Ni (50%wt) paint micropenetrated by Cu was about 20dB greater than that of high Ni(85%wt) paint,because Cu penetrating into Microhole nets of low Ni paint produced more chainpassages and electronic tunnels, raised conducting netdensity, and increased conductivity by ten times. We also inquired into theory about controlling conductivity of Ni paint.更多还原
