Preparation and Photocathodic Protection Properties of NiP/TiO2 Bilayer Coating on Low Carbon Steel
The NiP/TiO2 bilayer coatings were prepared on low carbon steel substates using a combined electroless plating and sol-gel method. The performance of photocathodic protection of the bilayer coatings was investigated by the electrochemical method. The results show that the coating with four TiO2 layers and calcined at 400°C exhibits the highest photoelectrochemical efficiency and the best corrosion resistance property.
