摘要:: 在总结了化学复合镀主要机理和沉积模型的基础上，从微观动力学和电化学两个角度入手，综述了微观形貌观察法、电化学研究法、电化学结合谱法等国内外关于纳米化学复合镀沉积机理的研究方法，并指出了各方法的优缺点。微观形貌观察法主要是借助于先进的形貌观察手段探讨复合镀层中各种微粒的运动规律，从而总结沉积机理。电化学方法则是应用混合电位理论，结合X射线谱、拉曼光谱、XPS等谱法分析，通过开路电位、极化曲线和伏安曲线电化学测量侧重讨论纳米化学复合镀过程中的沉积步骤、阴阳两极电化学反应反应速率、各沉积产物的沉积电位变化等内容，进而总结出复合镀层的沉积机理。最后，对纳米化学复合镀沉积机理研究方法的发展方向进行了展望。

Abstract:: Based on the summary of the main mechanisms and deposition models of the electroless composite plating, micro-dynamics and electrochemistry methods on the deposition mechanism of electroless nano-composite plating were reviewed both at home and abroad, including microstructure observation method, electrochemical method, electrochemical and spectral method, etc. Then, the advantages and disadvantages of every method were mentioned. The deposition mechanism of electroless nano-composite plating can be explored by the micro-dynamics method through observing and discussing transfer track of different particulates in composite coatings. On the other hand, applying the mixed potential theory, the deposition mechanism could be also clarified by electrochemical measurement methods with the combination of X-ray, Raman or XPS spectrum analysis. The open circuit potential, polarization curve and volt ampere curve can be measured and analyzed to reveal the deposition process, electrochemical reaction rates of cathode and anode, deposition potential of different deposition products in the electroless nano-composite plating, respectively. At last，the outlook for development of research methods on the deposition mechanism of electroless nano-composite plating was proposed.
