To mitigate the microbiologically influenced corrosion of metallic components serving in marine environments, an innovative Ag nanoparticle (AgNP)/NbC nanocomposite coating was synthesized using a double glow discharge plasma method. The coating was composed of Ag nanoparticles together with NbC nanocrystals embedded in an amorphous carbon (a-C) matrix. The incorporation of Ag into the NbC coating played a significant role in determining both the grain size and crystallographic texture of the NbC phase, as well as the bonding state of the carbon species and the surface morphology of the coating. Following immersion in sulfate-reducing bacteria (SRB)-inoculated artificial seawater, the planktonic SRB cell count for the AgNPs/NbC nanocomposite coating was found to be two and three orders of magnitude lower than those of the Ag-free NbC coating and bare Ti-6Al-4V, respectively. The electrochemical corrosion behavior of the AgNPs/NbC nanocomposite coating was evaluated and compared to the Ag-free NbC coating and bare Ti-6Al-4V in SRB-inoculated artificial seawater by using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The semiconducting properties of the oxide film grown on the nanocomposite coating were drawn from Mott–Schottky analysis. The results showed that Ag additions improved the microbiologically influenced corrosion (MIC) resistance of the NbC coating and led to the transformation of the electronic structure of the oxide film from an n-type semiconductor to a p–n heterojunction structure.

“…Non-carbide metals and carbon do not react, such as silver and copper, there is no hard phase generation, and the inherent good ductility characteristics of the metal can still be maintained after entering the interior of the film. In addition, the doped particles are in the nanometer scale, which can change the particle arrangement in the amorphous carbon matrix [40][41][42][43][44].…”

Diamond-like carbon (DLC) films have a promising tribological application in green precision manufacturing, but their toughness represents a serious issue in the way of their application perspective. The film thickness is on the micrometer scale and makes conventional methods unsuitable for its toughness characterization. The absence of an accepted method for characterizing the DLC toughness has hindered the related research on the development of toughening methods and understanding the mechanism. This work intends to explore a relatively simple and acceptable characterization method to measure the film toughness. Moreover, toughening mechanisms of DLC films are proposed during the characterization to reveal the toughening mechanism. The toughness can be fully characterized through combining impact toughness and scratch toughness. The impact toughness can be obtained by observing the size of the indentation and the crack state around the indentation in the impact experiment. The scratch toughness could be assessed by combining the scratch morphology and Crack Propagation Resistance (CPRS). The improvement of film toughness should be carried out from two aspects: preventing microcrack initiation and suppressing crack propagation. Appropriate doping of non-carbide metal particles can effectively improve the toughness of the film, and there are seven main factors affecting the toughening of the film. Five toughening mechanisms of non-carbide metals from film preparation to test stage are revealed during the investigation of the change patterns.

“…Researches on increasing the toughness of hard nitride coatings while maintaining their hardness has attracted considerable attention globally [7,8]. Currently, nitride coatings have been toughened via the ductile phase, gradient and multilayer structures, phase transformations, and nanocrystalline structures [9][10][11][12]. Hybrid materials comprising hard and soft phases possess both high hardness and toughness, such as MeN-M, where MeN represents hard nitride that possesses high hardness (such as CrN or TiN), and M represents the soft phase that provides excellent toughness properties [13].…”

This study determines the effects of nickel (Ni) doping on the composition, phase structure, chemical valence state, hardness, and toughness of CrAlNiN coatings. CrAlNiN coatings with various Ni contents (0.00 at%-27.71 at%) were deposited on the surfaces of M2 tool steel and monocrystalline silicon (Si) using unbalanced magnetron sputter ion plating. The results showed that the CrAlNiN coatings possess a nanomultilayer structure, maintaining the face centered cubic crystal structure of the chromium aluminum nitride (CrAlN) coatings. The Ni in the coatings acts as a toughening phase to ease stress, to increase resistance to crack growth, and to delay the generation of cracks, thereby having an obvious toughening effect. At an Ni content of approximately 20.33%, the Ni toughening phase in the modulation layer tends to saturate and the effect of continuing the increase in Ni content is limited from the viewpoint of improving the toughness.
