摘  要：
利用化学镀方法在桦木单板表面沉积Ni—Cu—P三元合金,考查施镀温度对镀后单板表面电阻率和电磁屏蔽效能的影响,采用扫描电镜(SEM)观察镀后单板的表面形貌,利用EDS和XPS分析镀层成分,利用X射线衍射(XRD)分析镀层的组织结构,采用直拉法测定镀层与木材表面的结合强度。结果表明:当温度从80℃升高到90℃时,镀层平均表面电阻率从0.451Ω/cm2降低至0.301Ω/cm2;继续升高温度,表面电阻率小幅升高;在90℃时,施镀单板的电磁屏蔽效能在9 k Hz~1.5 GHz频段达到55~60 d B。SEM观察发现镀层连续、致密且具有金属光泽;EDS分析可知镀层中存在Ni、Cu和P元素,XPS分析可知镀层组成为Ni、Cu、P,其质量分数分别为79.84%、11.82%和8.34%;XRD分析表明镀层为微晶态结构;镀层与木材表面结合牢固。

摘  要：
We used electroless plating to deposite Ni-Cu-P ternary alloy on birch veneer to study the effects of plating temperature on surface resistivity and electromagnetic shielding effectiveness. We observed the surface morphology of plated veneer by scanning electron microscopy( SEM),and analyzed the composition of the coating by energy dispersion spectrometer( EDS),X-ray photoelectron spectroscopy( XPS) and the structure of the coating by X-ray diffraction( XRD). We measured the bonding strength between the coating and wood surface by vertical pulling method. The mean surface resistivity decreased from 0. 451Ω / cm2 to 0. 301Ω / cm2 with increasing temperature from 80 ℃ to 90 ℃. However,the surface resistivity increased slightly with further increasing temperature. The electromagnetic shielding effectiveness of plated veneer was up to 55-60 dB in frequencies range of 9-1. 5 GHz at 90 ℃. By SEM,the coating was smooth,continuous and compact,and had metallic sheen. By EDS,the coating was composed of nickel,copper and phosphorus element. By XPS,the coating was composed of 79. 84% Ni,11. 82% Cu and 8. 34% P,respectively. The coating was microcrystalline state by XRD,and the coating firmly adhered to the wood surface.
