International. Iranian researchers studied the effect of the application of ceramic nano-coatings on improving the corrosion resistance of metal objects. Efforts have been made in this research to obtain the optimal operating conditions to achieve an optimal coating.
Corrosion is one of the unwanted reasons for reduction performance in industrial units, which decreases the service life of the units. Studies show that more than 20% of corrosion in a country is carried out in industrial units related to the oil industry.
Therefore, the researchers studied the coating of ceramic nanoparticles on steel or metal substrates and their performance. The possibility of creating a ceramic layer made of alumina - titania (Al2O3 - TiO2) nanoparticles on steel substrates has been studied by researchers from India through the electrochemical method. Therefore, an attempt was made to study and determine the effective and optimal properties in the coating process.
Electrochemical deposition methods, including electrophoretic deposition (EPD), are quick and simple and do not require expensive equipment. These characteristics are considered important advantages of this method in controlling the morphology of the coated surface, controlling the rate of the coating, the variety in the form of substrate and the lack of the need for glue. More homogeneous coatings can be created on steel substrates by using nanotechnology and nanostructured materials, which have higher corrosion resistance.
Taking into consideration the advantages of the electrochemical method and the reasonable price of ceramic particles, it can be said that the product is cost-effective. However, more research is needed to prove this claim.
