“…TiCl 2 powders were synthesized in a fluidized bed, where Ti powders were fluidized by Ar and reacted with TiCl 4 at 600°C. The details showed in our previous paper . Solid state TiCl 2 (s) powders (3.0 g) were sublimated into gas state TiCl 2 (g), and then it was transported to a reaction area to react with N 2 and H 2 or CH 4 in a tube furnace (6 cm diameter).…”

Preparation of high melting point sphere is of great practical value and remains a great challenge. Herein, for the first time a delicate chemical vapor deposition (CVD) process was developed for fabricating spherical TiN and TiC powders, which can hardly be attainable by conventional processes. The big equilibrium constant and released heats are key parameters for obtaining spherical TiN and TiC powders by the CVD process. Sphericity and crystallinity of these spherical powders can be controlled by adjusting nucleation and growth. The optimal TiN spheres (diameter 0.46 μm, sphericity 0.89) and TiC spheres (diameter 0.52 μm, sphericity 0.87) were obtained at 850°C under N2 and H2 and CH4, respectively. The design ideas explore a novel way to fabricate high melting point spheres.

“…This approach is highly costly and only suitable for the relatively planar substrates of simple geometry. In contrast, CVD utilizes the chemical reaction of low-cost gaseous Ti-containing precursors to form a solid Ti deposit on the substrate [16]. Chemical vapor deposition (CVD) is a versatile process widely utilized across various applications including the production of coating, powders, fibers, and consistent components.…”

Titanium alloys are utilized in various industries due to their remarkable strength-to-weight ratio, corrosion resistance, and biocompatibility. Nevertheless, their corrosion susceptibility is influenced by temperature, pressure, manufacturing methods, electrolyte properties, mechanical handling, alloy composition, surface passivation, constituent phases, and environmental conditions. Their corrosion resistance is largely determined by the passive film’s density, the chemical composition, and the base metal’s microstructure. These alloys face diverse corrosion challenges in different applications, necessitating the development of effective protective measures. This review examines the types of corrosion, the factors influencing it, and the specific issues encountered in various applications. Furthermore, it provides an overview of using functional coatings to enhance titanium alloys’ corrosion resistance. Based on recent research findings, the review evaluates multiple coatings, including thermal spray coating, chemical vapor deposition, cold spray coating, laser surface engineering, and laser surface alloying. It discusses the protective mechanisms of these coatings, such as barrier formation, passivation, and inhibition of corrosive species. Additionally, challenges related to coating adhesion, durability, and performance under extreme conditions are addressed. This analysis aims to shed light on the current state of functional coatings for titanium alloys and identify potential directions for future research to achieve more robust and durable corrosion protection.
