“…In particular the low wear and abrasion resistance of Ti alloys in biomedical applications has prompted extensive research into surface modification of these alloys in recent years [1,7,8]. Coating titanium and its alloys with hard and inert/biocompatible compounds has been rigorously investigated in the last decade, and it remains an active area of interdisciplinary research [9][10][11][12][13][14][15]. Various coating methods have been used to create thin coating layers on pure titanium, as well as commercial alloys such as Ti-6Al-4 V [1,15].…”

“…At the same time, some pores are visible in the coating. According to a reference report [16], these pores may be explained by gas trapping due to large fluid viscosity induced by aluminum particles in the melt pool and the encapsulated bubbles during the lasercladding process. The magnified cross-section SEM morphologies of the etched Ti 3 Al coating are shown in Fig.…”

“…However, titanium and its alloys have a high friction coefficient and low hardness, which make their tribological properties very poor and limit their engineering applications [7][8][9]. To improve the tribological properties of titanium and its alloys, some technologies such as ion implantation, physical-vapor deposition, chemical-vapor deposition, carburizing, nitriding, laser cladding, and oxidation have been studied [10][11][12][13][14][15][16][17][18]. Among these methods, laser cladding has been used to prepare the advanced coatings so as to protect the engineering components against friction, due to the fact that the high energy density of the laser beam and the coatings prepared by laser cladding are very dense and have strong metallurgical bonding to substrates [19].…”

Ti 3 Al coating was in situ synthesized successfully on pure Ti substrate by laser-cladding technology using aluminum powder as the precursor. The composition and microstructure of the prepared coating were analyzed by transmission electron microscopy, scanning electron microscopy (SEM), and X-ray diffraction technique. Thermal gravimetric analysis was used to evaluate the high-temperature oxidation resistance of the Ti 3 Al coating. The friction and wear behavior was tested through sliding against Si 3 N 4 ball at elevated temperature of 20, 100, 300, and 500°C. The morphologies of the worn surfaces and wear debris were also analyzed by SEM and threedimensional non-contact surface mapping. The results show that the Ti 3 Al coating with high microhardness, hightemperature oxidation resistance, and high temperature wear resistance. The pure Ti substrate is dominated by severe adhesion wear, abrasive wear, fracture, and severe plastic deformation at lower temperature, and severe adhesion wear, abrasive wear, plastic deformation, oxidation, and nitriding wear at higher temperature, whereas the Ti 3 Al coating experiences only moderate abrasive and adhesive wear when sliding against the Si 3 N 4 ceramic ball counterpart. In addition, the wear debris of the laser-cladding Ti 3 Al coating sliding and Si 3 N 4 friction pairs are much smaller than that of pure Ti substrate and Si 3 N 4 friction pairs at elevated temperature.

“…Cutting tools decline rapidly because of the high cutting temperature and high friction in machining between a tool and a workpiece material. Nitride treatment method can substantially reduce the friction coefficient of titanium alloys [8][9][10][11]. However, this method is unsuitable for cutting titanium alloys as lubricating and cooling measures in real time, and it changes the surface properties as well.…”

A long, quasi-homogeneous cold plasma jet was generated through a homemade cold plasma jet generating device. Friction-wear test and assisted cutting of Ti6Al4V were studied under air, nitrogen, and nitrogen cold plasma jet (NPJ) atmospheres. The friction coefficient under nitrogen jet was small, and the wear appearance was smooth at lowspeed friction. At high-speed friction, the friction coefficient under NPJ was the smallest, which declined by 70 % compared with that under air atmosphere. The scratches and adhesive traces on the friction surface were the lightest as well. The lubrication and cooling effects were not evident under low-speed cutting, whereas the NPJ enabled the radial force Fy and the average flank wear width VB to decrease by nearly 40-47 % respectively under high-speed cutting compared with the ones under air atmosphere. Results show that the NPJ assisted cutting has little influence on the surface roughness, residual stress, and work hardening of workpieces, while the machinability of Ti6Al4V can be effectively improved.
