“…This can be explained by the surface quality of the coating. As mentioned in Section 2, the surface roughness of the HVOF-PVD duplex coating is greater than that of the PVD monolayer due to the growth defects during the physical vapor deposition [55,58,66], and the rough surface will inevitably cause greater frictional resistance. Therefore, during the friction process, the friction coefficient of the duplex coating is higher than that of the PVD monolayer.…”

“…In particular, the substrate easily undergoes the serious plastic deformation under the heavy load conditions, which can thereafter lead to catastrophic delamination/flaking of the top PVD protective coating [48][49][50]. Many researchers have recently proposed a new "duplex coating" system based on HVOF and PVD [45,[50][51][52][53][54][55][56][57][58][59][60].…”

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.

“…A coating with high H/E* is regarded to have superior tough, and one with high H 3 /E* 2 is considered to be hard [6,7]. Once a time, many studies on coatings pursue high H/E* and H 3 /E* 2 , which means the coatings are hard and tough [8][9][10]. Again, no matter how high the H/E* and H 3 /E* 2 of a coating is, they only represent a coating's properties.…”

A novel criterion, plastic/elastic deformation work (W p /W e ), was introduced to identify the codeformation capacity of chromium-nitrogen (Cr-N) coating and titanium alloy system, which can be related to the coating/substrate adhesion. By changing the N 2 flow ( f N2 ), the Cr-N coatings were deposited on Ti6Al4V (TC4) alloy substrate to obtain Cr(N), Cr 2 N and/or CrN coatings, which could be related to the various deformation capacities. It indicated that the high W p /W e ratios of the metallic Cr(N)/TC4 systems deformed coordinately and attached well. Among the ceramic CrN x /TC4 systems, the single-phase CrN/TC4 exhibited higher W p / W e ratio of 1.71 than 1.52 and 1.61 of the Cr 2 N or Cr 2 N@CrN/TC4 and better adhesion. As a novel criterion, W p /W e ratio indicates the co-deformation capacity of a coating/alloy system, related to the failure mechanism and the adhesion of a coating to the substrate.
