Comparative Investigation on Corrosion Resistance of Stainless Steels Coated with Titanium Nitride, Nitrogen Titanium Carbide and Titanium-Diamond-like Carbon Films

“…The anodic peak was attributed to the film erosion in artificial saliva because the corrosive mediums can penetrate defects and microcracks of the film [40]. For Ti-DLC, it possessed a smooth anodic curve and a negative passive region, suggesting the less corrosion [26]. Normally, a low corrosion current density (I corr ) implies high corrosionprotection performance distinctly [37].…”

“…Ti-DLC films are formed through the co-deposition of DLC and biocompatible Ti. This process not only enhances the mechanical properties of the surface, such as hardness, toughness and tribological performance, but also improves its corrosion resistance, particularly stress corrosion resistance [23][24][25][26].…”

Experimental Study of Diamond-like Carbon Film on Aermet100 Steel and First-Principles Calculation of Interfacial Adhesion

“…Owing to good corrosion resistance, excellent wear resistance, low friction coefficient, and high hardness, diamond-like carbon (DLC) films have served as, for example, protective coatings in various tribological applications, where high speed, heavy load, and high temperatures are applied. − Although DLC films can be prepared by various deposition methods assisted by all types of hydrocarbon gases, ,− many issues exist. For example, high-energy ion bombardment is required to supply sufficient energy (beyond the permeation threshold) to promote the transition from the hybridized sp 2 bond to hybridized sp 3 bond, thereby facilitating the growth of films with more diamond-like characteristics. , In addition, the poor adhesive behavior between DLC film and substrate caused by high compressive residual stress and the mismatch of interfacial atomic bonding characteristics also limits its application. , Various methods have been applied to address this problem over the years, such as multilayer and functional graded structures being used to reduce interfacial strain and to enhance interfacial adhesion. ,, However, this multistep process is still comparatively time-consuming and therefore costly in production.…”
