Abstract
Crystal defects can enhance the properties of materials without changing the composition but introduction of high-density defects in coatings is challenging. Herein, plasma immersion ion implantation and deposition (PIII&D) is employed to produce high-density crystal defects in CrN coatings to improve the mechanical properties. PIII&D is demonstrated to introduce high-density crystal defects into the CrN coatings, especially at a bias exceeding 10 kV. As a result, a large number of dislocations are created and distorted Moire fringes are observed. The hardness increases significantly from 24.2 GPa to 35.6 GPa, while the fracture toughness is not compromised.
