“…The chemical surface heat treatment methods mainly include nitriding, carburizing, oxidating, and boronizing. Nitriding treatment is the most commonly used chemical heat treatment method for titanium metal surfaces, including gas nitriding, plasma nitriding, and laser nitriding [ 183 , 184 , 185 , 186 , 187 , 188 , 189 , 190 , 191 , 192 ]. The nitriding temperature of titanium metal is much higher than that of steel materials.…”

Titanium alloy has the advantages of high specific strength, good corrosion resistance, and biocompatibility and is widely used in marine equipment, biomedicine, aerospace, and other fields. However, the application of titanium alloy in special working conditions shows some shortcomings, such as low hardness and poor wear resistance, which seriously affect the long life and safe and reliable service of the structural parts. Tribocorrosion has been one of the research hotspots in the field of tribology in recent years, and it is one of the essential factors affecting the application of passivated metal in corrosive environments. In this work, the characteristics of the marine and human environments and their critical tribological problems are analyzed, and the research connotation of tribocorrosion of titanium alloy is expounded. The research status of surface protection technology for titanium alloy in marine and biological environments is reviewed, and the development direction and trends in surface engineering of titanium alloy are prospected.

Titanium alloys are acclaimed for their remarkable biocompatibility, high specific strength, excellent corrosion resistance, and stable performance in high and low temperatures. These characteristics render them invaluable in a multitude of sectors, including biomedicine, shipbuilding, aerospace, and daily life. According to the different phases, the alloys can be broadly categorized into α-titanium and β-titanium, and these alloys demonstrate unique properties shaped by their respective phases. The hexagonal close-packed structure of α-titanium alloys is notably associated with superior high-temperature creep resistance but limited plasticity. Conversely, the body-centered cubic structure of β-titanium alloys contributes to enhanced slip and greater plasticity. To optimize these alloys for specific industrial applications, alloy strengthening is often necessary to meet diverse environmental and operational demands. The impact of various processing techniques on the microstructure and metal characteristics of titanium alloys is reviewed and discussed in this research. This article systematically analyzes the effects of machining, shot peening, and surface heat treatment methods, including surface quenching, carburizing, and nitriding, on the structure and characteristics of titanium alloys. This research is arranged and categorized into three categories based on the methods of processing and treatment: general heat treatment, thermochemical treatment, and machining. The results of a large number of studies show that surface treatment can significantly improve the hardness and friction mechanical properties of titanium alloys. At present, a single treatment method is often insufficient. Therefore, composite treatment methods combining multiple treatment techniques are expected to be more widely used in the future. The authors provide an overview of titanium alloy modification methods in recent years with the aim of assisting and promoting further research in the very important and promising direction of multi-technology composite treatment.

“…Therefore, in order to improve the service life and reliability of titanium alloy actuators, it is of great significance to develop efficient anti-wear strengthening processes for titanium alloys. At present, nitriding technology is usually used to improve the surface hardness and wear resistance of titanium alloys, and the related nitriding technologies mainly include ion nitriding, gas nitriding, and laser nitriding [11][12][13][14][15]. Among them, ion nitriding technology, as a green nitriding method with less environmental pollution, has the characteristics of high activity, fast permeability and easy control of permeability.…”

TC6 titanium alloy, also known as Ti-6Al-1.5Cr-2.5Mo, is one of the most widely used titanium alloys in the aerospace industry due to its high specific strength, corrosion resistance and excellent mechanical properties. However, its poor wear resistance limits its application in some situations, such as aircraft actuators. To improve its wear resistance, this paper performs ion nitriding treatment on TC6 titanium alloy for aircraft cylinder and studies its wear performance. The ion nitriding test is conducted for 16 h at 820°C using a bell-type titanium alloy ion nitriding furnace. The nitrided specimen is divided into three parts: nitrided layer, diffusion layer, and substrate layer. The nitrided layer was 4.11 μm thick and consisted of TiN and Ti2N phases. The diffusion layer was 13.69 μm thick and mainly composed of a gap solid solution formed by N element solid dissolved in α-Ti. After nitriding, the surface hardness of the specimen increased to 1105.2 HV, which is 2.37 times higher than that of the matrix. The hardness-affected layer is about 200 μm thick. The wear rate is reduced by 99.78 % compared with that of the matrix, indicating that ionic nitriding greatly improves the wear resistance of TC6 titanium alloy. The wear mechanism of the nitriding specimen differs from that of the matrix, mainly due to abrasive wear, while the wear mechanism of the matrix is a combination of adhesive wear and abrasive wear.
