“…It has been speculated that an excellent coating is obtained when bonds between the film and the substrate is produced before a strong 572 Sukhpal Singh Chatha, Hazoor S. Sidhu Vol.11,No.6 bond within the film is formed. Strong bonding between the coating and the substrate has a unique significance when the coated metals are used in aggressive corrosive environment [17]. In general, the corrosion-erosion resistance of thermal spray coatings depends on the chemistry and morphology of coatings.…”

“…can be deposited on metals to improve their surface properties [5][6][7][8][9][10][11]. There are several techniques for the deposition of ceramics films and coatings on metal substrate, such as chemical vapor deposition (CVD) [12], physical vapor deposition (PVD) [13], plasma spraying [14], electrochemical deposition [15] and sol-gel process [5,6,10,[16][17][18][19][20][21][22]. The sol-gel method is an environmentally friendly technique of surface protection and had showed the potential for the replacement of toxic pretreatments and coatings which have traditionally been used for increasing corrosion resistance of metals.…”

a b s t r a c t Nanostructured TiO 2 thin films were deposited on AISI 304 austenitic stainless steel by sol-gel process, dip coating technique. Influence of the number of layers, addition of polyethylene glycol (PEG) in initial sol, morphology and the surface roughness parameters of titania films on corrosion resistance of coated stainless steel were examined. Prepared films were characterized by SEM-EDS and AFM analysis. Electrochemical corrosion behavior of the coated stainless steel substrates was evaluated in simulated marine environment in 3 wt.% aqueous NaCl solution by electrochemical impedance spectroscopy (EIS) and in 0.5 M aqueous HCl solution by potentiodynamic polarization.

“…One of the methods for improving the adhesion of the alumina particles to metal substrates is surface modification using phosphate treatment [10]. Phosphating is a treatment on the metal surface to achievean insoluble coating from the phosphated metal crystals, which strongly adheres to the base metal.…”

In this research, Aluminum Oxide nanoparticles were made using the Sol-Gel methods, coating on phosphated substrate on Inconel 718. The study crystal structure and surface morphology respectively by FE-SEM and XRD Analysis were performed. Evaluate the properties of abrasion, by Test Pin-on-disc and calculated hardness variations by Microhardness test was performed on the coatings. The Polarization tests were used for study the corrosion resistance properties coating. The XRD results of coatings heat treated in 300, 500 and 800 °C, confirmed was amorphous nature of coatings. Just in the coating heat treated at 800 ° C can be weak peaks of gamma phase alumina (γ-Al2O3) can be seen. The FE-SEM images of the samples indicate, Coating particle size contains 46 nm and just uniform structure and free of porosity can be observed in the coating heat treated at 300 °C. The results of the test abrasion showed that phosphate substrate surface increases the wear resistance of the alumina Coating. The corrosion tests showed that the synthesis of nano-alumina Coating on phosphate surface of Inconel 718 alloy had a great effect on increasing corrosion resistance.
