| Abstract: |
| Due to the high adhesion strength between PVD hard film and metal, as well as the dense structure, good mechanical properties, excellent wear and corrosion resistances of the film, the work aims to deposit a protective film with superior tribo-corrosion and antibacterial characteristics on the metal surface to ensure the long-term use of metallic material in the wear/corrosion environment. Meanwhile, the films can also isolate the salt and microorganisms in the corrosive environment from direct contact with the surface of metallic material. Therefore, the traditional binary nitride films were introduced at first, and then in response to the growing demand for the wear resistance, corrosion resistance, and antibacterial properties of films, the effects of Si, C, Mo and Ag doping on the tribological properties of PVD films in air and water, the electrochemical corrosion and tribo-corrosion properties in the salt solution and seawater, the static and friction-induced antibacterial performances were reviewed. The traditional binary nitride films gradually developed into the multi-component CrMoSiCN-based films and in this process, the close relationship between mechanical and tribological characteristics was analyzed for films prepared at the different flow rates of reactive trimethylsilane gas and various sputtering currents of Si, Mo and Ag targets. The synergistic and cooperative relationships among abrasive wear, oxidative wear and electrochemical corrosion were described for films in the corrosive solution. The mechanism evolution of anti-microbial adhesion and antibacterial properties was elucidated for films under the various Mo and Ag contents. The friction coefficient and tribo-corrosion material losses of multi-component nitride-based films in the salt solution were strongly affected by the doped amounts of Si, Mo and Ag elements, and then the self-lubrication and anti-wear roles of films were effectively enhanced by the oxidation and corrosion products during the friction process. The bactericidal ability of nitride-based films was mainly related to the formation of MoOx oxide on the friction surface as well as the release and diffusion of Ag+ in the bacterial solution. Currently, if the Ag elements are doped into the CrMoSiCN-based films, it can not only improve the mechanical properties, wear resistance, corrosion resistance, and tribo-corrosion characteristics of films, but also endow them with unique antibacterial performance, thereby reducing the adhesion and interactive corrosion of microorganisms. However, the attention should also be paid to following issues in the research process. For example, the modification method through Ag doping may no longer be applicable for films especially in the high-pressure and rich oxygen environments, because the electrochemical corrosion results indicate that the corrosion resistance of films may be directly deteriorated by the excessive incorporation of Ag element. The various wear or tribo-corrosion tests of multi-element nitride-based films have not been yet completed under the wide ranges of temperature. The microbial/electrochemical coupled corrosion mechanisms should be worthy of in-depth researches for the multi-component nitride-based thin films. For the marine environment, the anti-adhesion behavior of film surface against microalgae and multiple sediments (excluding bacteria) has not yet been revealed. |
