| Abstract: |
| It mainly investigated the impact of various contents of TiO2 nanoparticles and different surfactants in nanocomposite plating bath on the performance of Ni-TiO2 nanocomposite coating, which were prepared on Q235 lowcarbon steel by electro-brush plating. The surface microstructure of composite coatings was studied by SEM. Thecorrosion electrochemical behavior of Ni-TiO2 nanocomposite coating in NaCl solution was studied by polarization curve. The results show that Ni-TiO2 nanocomposite coatings have smaller grain and lower porosity compared to pure Ni coating. The best coating was made by cationic surfactant to disperse bath. While TiO2 nanoparticle content was 10g/L in plating bath, the coating had the best corrosion resistance. And the coating had the best corrosion resistance by cationic surfactant to disperse bath while plating bath have the same TiO2 nanoparticle content. |
