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.
