- 1996年第2卷 
本文报道了铝蜂窝屏蔽通风窗化学镀磁性镍层和非晶态镍层的工艺研究结果．试验与产品镀复结果证明所得镍层外观光亮、厚度均匀、与铝及铝合金基体结合力优良，具有良好的导电、导磁和耐腐蚀性能．可满足电子设备、波导及屏蔽室等方面对电磁屏蔽性能的要求This report summarizes the electroless plating process of magnetic nickel and noncrystalline nickel for aluminium honeycomb shielded vent windows. The test results showed that the electroless nickel plating is bright in appearance, even in thickness, excellent in adhesion with aluminium substrate, good in conductivity, magnetism and corrosion resistance. Shielding efficiency obtained was 67～78 dB under 4 GHz～12 GHz frequency. Environmental reliability tests were made for 56 days under two environmental conditions, that is at 85 ℃ and 35 ℃, 95% relative humidity. The EMI shielding technical requirements of the electroless double nickel plating for aluminium honeycomb shielded vent windows of electric appliances, wave guides and shielded rooms have been met in practical use.
