ARTIFICIAL NEURAL NETWORK AIDED DESIGN OF FORMATION OF TiO_2 MODIFIED FILM ON CARBON STEEL

TiO2 modified film is one of wonderful anticorrosion materials. TiO2 modified film on carbon steel was prepared by a new method-electroless plating and sol-gel composite process. There were many preparation factors influencing the corrosion resistance property of modified film, among them, the thickness of NiP transient layer (measured by plating time), number of dip-coating during the sol-gel process, heat treatment time and the molar ratio of complexing agent and Ti (OC4H9)4 were the most important ones. An artificial neural network was applied to design the preparation condition of TiO2 modified film considering the interaction of the main factors. The condition of forming TiO2 modified film on carbon steel was that NiP plating was 50minutes, No.of dip-coating was 4, heat treatment time was 2 hours, and the molar ratio of complexing agent and Ti(OC4H9)4 kept 1.5: 1. Corrosion behavior of TiO2 film on carbon steel was investigated by polarization resistance measurement. The result shows that electroless plating and sol-gel TiO2 modified film on carbon steel has a good anticorrosion property in 0.5 mol/L H2SO4 solution
