Study on the Preparation and Corrosion Resistance of Nano-Structured SiO2 Thin Film on Carbon Steel
Used RF magnetron sputtering method to prepare SiO2 thin film on the carbon steel (Q235A) substrate, Films were characterized with the atomic force microscope (AFM) and the X-ray photoelectron spectrum (XPS). Corrosion resistance was compared of SiO2/ Q235A and Q235A. The results showed that: nano-structured thin film was smooth and dense, The thin film was constituted by compact particles of SiO2, and there was no Fe in the films. Electrochemical experiments indicated that SiO2 / Q235A had better corrosion resistant than Q235A in the sea water.
