摘  要：
采用化学镀法在桦木表面获得Ni-P合金镀层。利用傅立叶红外光谱(FTIR)和X射线光电子能谱(XPS)技术,分析桦木单板化学镀前预处理后,桦木表面官能团的变化和化学镀后元素的变化。FTIR分析表明:分别经活化和解胶处理后的桦木单板表面FTIR谱与素材几乎重合,表明活化和解胶处理过程没有使木材表面发生任何化学反应。XPS分析结果表明:活化后桦木单板表面吸附了内部包裹着具有催化作用的Pd0胶粒,此时Pd0起不到催化作用;解胶后,Pd0才显露出来并催化化学镀反应的进行,但化学镀过程之初是Ni先沉积而P的沉积滞后,所得镀层成分为Ni-P合金。

摘  要：
Ni-P alloy coating was obtained by electroless plating on the surface of birch veneer. The variation of function group and element on it was analyzed in the pre-treated and plated process by FTIR and X-ray photoelectron spectroscopy(XPS) analysis technology. It was shown by FTIR analysis that FTIR spectrums of birch veneer activated and dissolved colloid were almost the same with that of untreated one, which indicated that the structure of birch surface activated and dissolved colloid was not changed. It was shown by XPS analysis that colloidal particle which contained Pd~0 core with catalyzing function was absorbed on the surface of activated birch veneer. However, Pd~0 in the core can't catalyze the following electroless plating. After dissolved colloid, Pd~0 was exposed to catalyze the electroless plating. In the beginning of electroless plating, Ni initial deposition was prior to P. The composition of the coating obtained was Ni-P alloy.
