The inherent defects in the 2D materials severely limit their application in several engineering applications, including their use as protective coatings in corrosion applications. The current study focuses on developing methods for rationally designing and synthesizing copper crystals with specific crystallographic orientations such as (111), (110), and (100) using Czocrhalski (CZ) process. Hexagonal Boron Nitride (h-BN) was grown on copper crystals using chemical vapor deposition technique, and the quality of the h-BN coatings was evaluated using Raman Spectroscopy. The specimens were exposed to sulfate-reducing bacteria, and the microbial corrosion resistance was investigated. The crystallographic orientation of the crystals was characterized using X-ray diffraction and electron backscatter diffraction techniques. The mechanical properties of the single copper crystals, such as hardness and modulus, were characterized using the nanoindentation technique. The effect of crystallographic orientation on the h-BN quality and the electrochemical behavior was investigated.
