“…The wear volume of the film and substrate in the acetic acid solution is higher than that in the aqueous solution due to the higher corrosiveness of the acetic The prepared Ti/TiN/a-C:H:Ti films were subjected to friction tests under atmospheric conditions. As shown in Figure 5, the three-dimensional profile of the abrasion marks shows that the abrasion marks are mainly characterized by furrow wear [24], and the depth of the abrasion marks becomes shallow with increasing Ti current and is lowest at 2 A. From the photomicrographs of the wear spots of the dyadic balls, it can be seen that there are carbon films on the surface of the balls, and the adhesion is slight at the Ti-2 A.…”

To meet the requirements of friction and corrosion resistance performance of helicopter transmission bearings under harsh environments, Ti/TiN/Ti-DLC multilayer composite films were prepared on a 40Cr15Mo2VN substrate by a non-equilibrium magnetron sputtering technique. The effects of different titanium currents on the structure, mechanical properties, and friction properties of the films were investigated by SEM, Raman spectroscopy, and nanoindentation. Moreover, the tribological and corrosion resistance of developed films under acidic conditions were investigated. The results show that the sp3-C/sp2-C ratio in the films gradually decreases with increasing Ti current from 0 A to 2 A, leading to decreased hardness and elastic modulus. The bonding force of the DLC films also gradually increases with increasing Ti current and reaches the maximum value of 41.69 N at 2 A; the friction coefficient of the films gradually decreases under a load of 20 N. In summary, the best performance of thin film at Ti-2 A was compared with the corrosion and wear performance of thin film and substrate in acetic acid solution and aqueous solution at Ti-2 A. The wear amount of thin film and substrate in aqueous solution is significantly lower than in acetic acid solution, and the corrosion potential of thin film is higher than that of substrate in both solutions, which can play a protective role against the substrate.

“…It is worth mentioning that DLC-covered HVOF coa has a phase angle closer to 90°, a higher impedance modulus, and a larger capacitive resistance radius compared to CrN. This indicates that the chemically inert DLC can prove the corrosion resistance of HVOF coatings more significantly than CrN [81] short, the corrosion resistance of HVOF-PVD duplex coating is distinctly better than of HVOF coating, and it is closely related to the type of PVD coating. In addition to electrochemical corrosion, chemical corrosion is also another comm corrosion phenomenon that produces loss and damage to materials [82,83].…”

The paper summarizes the current development of high-velocity oxygen–fuel coupled physical vapor deposition (HVOF-PVD) duplex coatings as protective candidates. Following a detailed historical overview of HVOF and PVD technologies, the fabrication methods for duplex protective coatings are presented. The duplex coating superimposes the synergistic advantages of coatings deposited by HVOF and PVD, where the traditional weaknesses of each technique are modified to a great certain extent. Subsequently, the relation between structural characteristics of the duplex coatings and their mechanical, tribological, and corrosive behavior is described in detail. It is demonstrated that the duplex coatings show more excellent overall performance than coatings deposited by both HVOF and PVD separately. Finally, we summarize the protective performance and promising potential of HVOF-PVD duplex coating for applications as well as the research prospects of challenges in future.
