The corrosion-reprieve effect of low-carbon steel

A new effort aims to develop a new coating based on shell polysaccharine titanium dioxide (CS / TiO 2) nanocomposomes to assess its corrosion-repelling effect on low-carbon steels.
(CS / TiO2) uses sol-gel, immersion technology, and coats nano-composite films on low-carbon steel surfaces.
coatings tailored to the corrosion resistance of metal substrates are highly relevant to ensure the reliability and long-term performance of coating components and the product value of coating materials

. At present, in different technology applications, great emphasis is placed on the development of advanced functions and intelligent coatings for corrosion protection. Shell polysaccharide titanium dioxide (CS / TiO 2) nano-composite film is applied to low carbon steel by sol-gel method. Sol-gel protective coatings have demonstrated excellent chemical stability, oxidation control and enhanced corrosion resistance of metal substrates.
environmentally friendly surface protection technology
In addition, the sol-gel method is an environmentally friendly surface protection technology that has traditionally been used to improve corrosion resistance of metals. The project uses solution casting method, titanium tetrate (TBT) as the prelude, acetyl acetone as the chelating agent, prepared shell polysaccharide titanium dioxide (CS / TiO 2) nano-composite film. Apply the prepared nano-composite film to a polished metal surface, dry and de-ignite at 120 degrees C for 2 hours. The corrosion protection behavior of these coated low carbon steel substrates in 0.1N HCl solutions was evaluated through the Motion Polarization Study (Tafel), linear polarization Study (LPR), and electrochemical impedance spectrum study (EIS).
