“…Researchers have studied the effects of Ni addition on the mechanical properties of chromium nitride (CrN) coatings by the Physical Vapor Deposition (PVD) technique, and the results showed that nickel could improve the toughness of chromium nitride coating. In previous research concerning nickel toughen CrN coating, much efforts have been paid to the property analysis such as toughness, wear resistance, and plastic deformation resistance of the coatings 23–33 . However, electronic structure and bonding nature in the interface region between CrN and Ni have seldom been reported.…”

Atomic structure, adhesion energy, and electronic properties of the bonding nature at CrN(200)/Ni(111) interfacial region are studied by first‐principle calculations based on density functional theory (DFT). A new method for building the heterostructure of CrN(200)/Ni(111) is proposed to solve the large lattice mismatching between CrN(200) and Ni(111) slab. Three models (OT, ST, and TL) with different interface distance are built up, and the total energy for each of them is calculated. Comparing with other stacking sequence, TL sites with 1.9‐Å spacing at the interfacial region shows the biggest value of adhesion energy after geometry relaxation. Furthermore, the contour of charge density, partial charge density of states, and Bader charge values of the TL sites with 1.9‐Å spacing are plotted out and calculated. Results indicate that covalency bonding between Ni and N ions and metallic bonding between Ni and Cr atoms are formed at the interfacial region.
