“…1100°C without any subsequent heat treatment produces coatings with similar mechanical properties to that of bulk material. Cavaliere et al [108] evaluated the microstructural and mechanical characteristics of cold gas dynamic sprayed Ni and Ti-based coating. Ti and NiCrAlY coatings were deposited on Ti6Al4V and IN718 substrate.…”

Thermal spray coatings are a group of coating processes that enhance the performance of parts by adding functionality to surfaces. In the past few decades, thermal spray coatings technology was used to resist wear, erosion, corrosion, cavitation, repair and dimensional restoration of parts. However, the consideration of process parameters setting develops a reliable coating having high mechanical and morphological properties for demanding coating applications. Hence the aim of this review paper is to provide an overview of distinct thermal spray coatings, historical development, hot corrosion mechanism and effect of chemical composition and alloying elements on the hot corrosion resistance of super alloys in USC power plants. Then the effects of processing conditions on the mechanical properties of distinct thermal sprayed coatings obtained at distinct process parameters are summarised. Finally, the distinct thermal post treatments such as fusing of self-flux alloys, remelting and solid heat treatments, merits, demerits and future challenges are discussed.

“…Cold-sprayed Ti and its alloy has the ability to rapidly fabricate thick and un-oxidized coatings and are used for the protection of steel structure or component in harsh/ aggressive marine environment. These alloys are also used to enhance the biocompatibility and integration of the implant [55-57]. The microstructure of Ti powder &as-sprayed Ti coating is depicted in Figure 12.…”

Cold spray is an emerging surface coating technology for rapidly developing thick coating, thin films and additive manufacturing of parts at relatively low temperatures. The low cost and scalability of a cold spray method make it promising for diverse industrial applications. Presently, the cold spray coating is widely used for the production of machine parts, materials and tools that requires the desired surface properties. However, the consideration of process parameters setting develops a reliable coating having high mechanical, tribological, fatigue and morphological properties for demanding coating applications. Hence, the aim of this paper is to study the effect of processing conditions (pressure and temperature of propellant gas, powder particle morphology and post-process treatments) on the tribological and mechanical properties of cold-sprayed coatings. Further, the effect of microstructure and processing conditions on the fatigue and static characteristics of cold spray material is also discussed.

“…The results showed that with 2198 Al alloy repair, the crack resistance increased by more than seven times, and CS repair helped increase the cracked structure’s overall fatigue life. Cavaliere et al [ 71 ] prepared Ti- and Ni-based nanocomposite coatings by CS technology for the repair study of Ti alloy substrates. The experimental results showed that CS could successfully deposit dense Ti coatings for repairing Ti alloy parts.…”

This paper systematically introduces the application status of coating-preparation technology on light alloys in the field of aviation parts repair. Included are the advantages and disadvantages of thermal spraying technology and laser cladding technology in the application process, as well as the research status and application prospects of the emerging cold spray (CS) technology and supersonic laser deposition (SLD) technology. Compared with traditional thermal-spraying technology, CS has many advantages, such as low spraying temperature, low oxygen content of the coating, and low porosity, which can effectively avoid oxidation, burning loss, phase change, and grain length during thermal spraying. CS can prepare oxygen-sensitive, heat-sensitive, amorphous, and nanomaterial coatings that are difficult to prepare by traditional thermal-spraying technology. However, in the preparation of high-strength super-hard alloys, CS has shortcomings such as low deposition efficiency and bonding strength. SLD overcomes the shortcomings of CS while inheriting the advantages of CS. In the future, both technologies will be widely used in repairing and remanufacturing in the field of aviation. Based on the principles of CS and SLD, this paper introduces, in detail, the deposition mechanism of the coating, and the specific application examples of CS in the aviation field at the present stage are described. The research and application status of the two technologies in the fields of anti-corrosion coating, wear-resistant coating, functional coating, repair, and remanufacturing in recent years are reviewed. Finally, the application and development prospects of CS and SLD are discussed.
