“…Therefore, titanium alloy materials are often subject to thermal corrosion caused by salt deposition, resulting in reduced engine efficiency, increased fuel consumption, and reduced service life [6]. In addition, titanium alloys have the disadvantages of poor wear resistance and low thermal conductivity during use [7], which leads to premature failure of high-temperature components and a greatly reduced service life. A high-temperature and complex environment is extremely harmful to the titanium alloy substrate, which greatly limits the application range of titanium alloys and their internal field application under sliding conditions.…”

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.

In this work, low‐cost TiC/Ti composites with high strength‐ductility and superior abrasive resistance were fabricated using hydrogenation‐dehydrogenation (HDH) powder and graphene nanoplates as raw materials via spark plasma sintering (SPS) and hot rolling (HR) processes. Effects of in‐situ TiC contents on the microstructure, mechanical properties and wear behavior of the TiC/Ti composites were investigated. The results indicate that the microstructure after HR is equiaxial α‐Ti grain with random orientation. The TiC/Ti composites exhibit higher strength compared to pure Ti matrix after HR. The ultimate tensile strength of the 1.82vol% TiC/Ti composite is 1059 MPa, which represents a 49.3% increase compared to pure Ti. The coefficient of friction of the TiC/Ti composites decreases from 0.51 to 0.43 with an increase in TiC contents. The improvement of strength is attributed to refinement strengthening, dislocation strengthening and TiC load transfer. In addition, the increase of TiC contents will reduce the friction coefficient of the composites, thereby improving the wear resistance of the composites. The paper proposes a cost‐effective method with good prospects for industrial applications to improve the mechanical properties and wear‐resistant properties of the titanium alloys.This article is protected by copyright.
