Special Issue Information

Dear Colleagues,

Many researchers have studied surface engineering to explore superior coatings deposited onto metallic materials to overcome deterioration. As a new thermal spraying technology, high-velocity oxygen fuel (HVOF) technology has the characteristics of fast particle flight speed, low temperature, and high bonding strength and is widely used in the machinery, electric power, metallurgy, aviation, and petrochemical industries for surface protection and repair of metal materials. HVOF spraying involves a series of complex physical and chemical reaction processes, and the control parameters of the spraying process are complex. There are many spraying process parameters that affect coating quality. It is necessary to study the influence of process parameters on the physical and mechanical properties of coating by means of experiments and simulations. Under the current international dual-carbon goals, green manufacturing and materials with low pollution, low energy consumption and high performance are becoming more and more important. HVOF spraying technology can extend the life of related components and provide a new way for the world’s low-carbon green manufacturing.

This Special issue will serve as a forum for papers in the following concepts:

  1. Experimental study and numerical simulation of HVOF spraying mechanism;
  2. Study on the correlation between the preparation process of HVOF coating and coating properties;
  3. Industrial applications of high-performance HVOF coatings;
  4. Explore the many possibilities of HVOF coatings;
  5. Research prospect of HVOF spraying and coatings.

Three-dimensional computational fluid dynamics (CFD) modelling is employed to simulate a typical high velocity oxygen fuel process (HVOF) under laboratory operating conditions. Two different modelling approaches, viz., the continuum and discrete models, are engaged to model the liquid fuel kerosene, and their influence on the resulting primary gas dynamics is investigated. Numerical results of the primary gas dynamics are validated against the available measurements and found to be in good agreement. It is observed that the fuel droplets less than 5 μm react completely inside the combustion chamber, whereas the larger droplets do not. With increasing fuel droplet size, the chemical reaction gets extended to the downstream of the combustion chamber, resulting in decreased flame temperature. Thus, it is inferred that a fuel droplet size of up to 5 μm yields better combustion characteristics. Discrete solid CoNiCrAlY particles are then injected into the high velocity primary gas stream, and their inflight dynamics are simulated. Results reveal that a maximum mean particle velocity of 700 m/s and a maximum particle temperature of 1350 K may be achieved under the given operating conditions. Particle deposit shape and size are determined both numerically and experimentally and found to be in good agreement. The influence of substrate stand-off distance on the particle deposit characteristics is investigated and reported in detail. Full article

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. Full article
