Abstract Scope |
Iron is commonly used in a wide range of applications, such as structures, automobiles, pipelines, and machinery components. However, mild steel is prone to aqueous corrosion when exposed to humidity and often requires a corrosion-resistant coating. Recently, hexagonal boron nitride (hBN) coatings grabbed significant interest because of their excellent anti-corrosion properties. This research aimed to examine the effect of a thickness (25nm, 50nm, and 100nm) of pulsed laser-deposited hBN coatings on the corrosion rate of iron. Microstructural characterization and phase identification of coatings was performed using scanning electron microscopy and RAMAN spectroscopy. Confocal laser scanning microscopy was used to characterize the surface roughness of the coatings, and preliminary results showed that surface roughness increased with an increase in the coating thickness. The electrochemical impedance spectroscopy and Tafel plots were used to evaluate the corrosion properties of hBN-coated iron substrates and were compared with bare substrates with no hBN coatings. |
