The main objective of this work is to investigate the microstructure, mechanical properties, and corrosion behavior of various substrates modified with nanolayers of hexagonal boron nitride (hBN) using pulsed laser deposition (PLD) process. Microstructural characterization and phase identification were performed using scanning electron microscopy and X-ray diffraction. Raman spectroscopy was employed to characterize the quality of hBN coatings. The surface roughness of the coatings was analyzed using Atomic force microscopy. The mechanical properties, such as the hardness and modulus of the hBN nanofilms, were characterized using the nanoindentation technique. The electrochemical properties of coated and uncoated substrates were carried out using tafel plots and electrochemical impedance spectroscopy measurements. The resultant microstructure and mechanical properties of the films were correlated to the PLD process variables.
