Ti/steel clad plate is usually prepared by high energy plasma spray technology, which is hard to avoid pores and cracks degrading the performance of Ti film. Therefore, several kinds of representative commercial organic coatings and nano-modified acrylic coating were used for the hole sealing treatment. The surface structure of Ti film and combination with organic coatings were observed by SEM. Moreover, electrochemical test and salt spray tests were conducted to compare different corrosion resistances of Ti/steel clad plates with organic coatings. In conclusion, the results showed that nano-modified acrylic coating was more suitable as a hole sealing coating for Ti/steel clad plates due to the synergistic protection of sprayed Ti film and nano-modified acrylic coating.
