Au-Ni-TiO2Nano-Composite Coatings Prepared by Sol-Enhanced Method

Abstract: Gold coatings are widely used in many fields for their shining color, excellent corrosion resistance, and electrical conductivity. However, they are not mechanically strong with low wear resistance. In this paper, we have prepared nano-composite Au-Ni-TiO 2 coatings by our newly developed sol-enhanced electroplating method. In order to obtain the optimal mechanical properties, a systematic study of Au-Ni-x TiO 2 coatings with different sol concentrations (x is the sol doping concentration from 0 to 25 mmol/L) … Show more

“…Comparing with the Chromium (Cr) [19] or Nickel (Ni) [20,21] , which are the mostly used coating, Cu-Sn-Zn coating possesses a relatively soft hardness. In order to improve the mechanical properties and explore the application of Cu-Sn-Zn coatings, the preparation of Cu-Sn-Zn based nano-composite coatings, i.e., incorporating the second phase or other nanoparticles into coating matrix, could be a potential solution [20][21][22][23].…”

“…The small particles in sol with the charge on the surface cannot grow up for the covered layer of solvent molecules. Different small particles can be well suspended in the solvent, subjecting to the combined effect of charge, van der Walls force and gravity [9][10][12][13]. The hydrolysis reaction and condensation process of TiO 2 sol has been widely investigated.…”
