“…As a consequence, under the common action of the TiC particles and matrix microstructure, the oxides formed on the as‐rolled composite were significantly refined, as shown in Figure 7b,d. The refined and dense oxides in the surface can impede both the internal diffusion of oxygen and the outward diffusion of Ti, [ 35 ] resulting in significant reduction of the oxide layer thickness shown in Figure 8b and 9b, and then contribute to enhancing the oxidation resistance.…”

Herein, the 5 vol% TiCp/Ti–6Al–4V composite is prepared by induction skull melting (ISM) and direct rolling in near‐β phase region. The microstructure, mechanical properties, and high‐temperature oxidation behavior of the as‐cast and as‐rolled composites are systematically investigated. The investigations of microstructure reveal that the as‐cast coarse α/β lamellar matrix microstructure is translated to refined bimodal microstructure after direct rolling. And the coarse and segregated TiC particles tend to be refined and uniformly distributed in the matrix. Tensile test results exhibit that a well‐matched strength and elongation is obtained after direct rolling. The tensile strength at room temperature (RT) and high temperature (650 °C) increases to 1291.9 and 472.5 MPa, respectively, while the as‐rolled composite maintains a good elongation of 6.7% and 26.8%, respectively. The strengthening mechanism can be attributed to grain boundary strengthening and the load‐bearing capability of TiC. Isothermal oxidation test indicates that as‐rolled composite exhibits better oxidation resistance than as‐cast composite both at 550 and 650 °C. The improved oxidation resistance is mainly a result of the significant refinement of oxides and consequently retarding the diffusion process.

“…The addition of increasing percentage in Y reduced the grain size of the oxide layer, which decreased oxygen diffusion and increased the alloys' oxidation resistance. The addition of yttrium improves the adhesive strength between the oxide coating and the base material [14]. However, the inclusion of rare-earth oxides increased the oxygen concentration of the coatings.…”

Because of inadequate hardness, low resistance to wear, and excess friction coefficient of titanium, and its alloys are limited in their applicability. Cladding, a type of surface modification process, is used to create layers on titanium and its alloys that have superior mechanical qualities, wear characteristics, oxidation resistance at high temperatures, and good biocompatibility. Material selection is critical for achieving the increased qualities mentioned above, in addition to various cladding techniques and associated process parameters. A review of the outcomes of various common wear-resistant cladding techniques applied to the titanium alloy surface is the subject of this study. The most important functional claddings in this domain are also presented and investigated in depth. The present issues and future initiatives are also discussed, with an emphasis on identifying knowledge and technological gaps as well as attempting to establish future research possibilities. On this foundation, it is suggested that in the coming years, resistant-to-wear cladding with significant improvements in toughness and hardness should progress on the path of smart manufacturing techniques, optimising and precisely customising microstructural configurations, and developing numerical simulation techniques of cladding.

At present, in the aviation industry, titanium alloy is mainly used to manufacture parts such as compressor discs, blades, and the casings of aircraft engines. When titanium alloys are in service, high temperature is generated due to high-speed running friction, which requires them to have high-temperature oxidation resistance and friction resistance. If they are used in an environment with salt corrosion, titanium alloys will face thermal corrosion, which limits their wider practical applications. At present, there are many methods to protect titanium alloys. This paper mainly includes alumina-based coatings and some preparation methods. The characteristics and functional mechanisms of three functional coatings for the service environment, namely highly temperature-resistant alumina-based coating, thermal corrosion-resistant alumina-based coating, and wear-resistant alumina-based coating, are summarized. Finally, the development direction of composite coatings of titanium and titanium alloys for a complex service environment is suggested.
