摘要:

在總結(jié)了化學(xué)復(fù)合鍍主要機(jī)理和沉積模型的基礎(chǔ)上，從微觀動力學(xué)和電化學(xué)兩個角度入手，綜述了微觀形貌觀察法、電化學(xué)研究法、電化學(xué)結(jié)合譜法等國內(nèi)外關(guān)于納米化學(xué)復(fù)合鍍沉積機(jī)理的研究方法，并指出了各方法的優(yōu)缺點。微觀形貌觀察法主要是借助于先進(jìn)的形貌觀察手段探討復(fù)合鍍層中各種微粒的運動規(guī)律，從而總結(jié)沉積機(jī)理。電化學(xué)方法則是應(yīng)用混合電位理論，結(jié)合X射線譜、拉曼光譜、XPS等譜法分析，通過開路電位、極化曲線和伏安曲線電化學(xué)測量側(cè)重討論納米化學(xué)復(fù)合鍍過程中的沉積步驟、陰陽兩極電化學(xué)反應(yīng)反應(yīng)速率、各沉積產(chǎn)物的沉積電位變化等內(nèi)容，進(jìn)而總結(jié)出復(fù)合鍍層的沉積機(jī)理。最后，對納米化學(xué)復(fù)合鍍沉積機(jī)理研究方法的發(fā)展方向進(jìn)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.
