“…The wear resistance of Ti-6Al-4V has been improved by different surface engineering methods such as anodic oxidation (i.e., anodizing [10] and plasma electrolytic oxidation [11]), physical and chemical vapor deposition [12,13], surface melting and alloying [14], stirred friction processing [15], diffusion based treatment [16] ,thermal oxidation [17] and boost diffusion oxidation [18]. Among them, the thermal oxidation is an effective and environmentally friendly technique.…”

Oxygen diffusion layer (ODL) was produced on Ti-6Al-4V by thermal oxidation at a temperature of 850 °C for 3 and 6 h. Hardness of the samples was measured using a nano-indentation tester.Micro-scratch tests were performed under progressive and constant normal loads of 0 50 N. Dry wear behavior of the samples was studied using a ball-on-disk tribometer. The wear tests were carried out under various normal loads of 7.5, 15 and 30 N for sliding distances of 50, 100, 200 and 300 m using alumina balls as the counterface. The wear and scratch tracks were examined by scanning electron microscope and surface profilometer. The ODL samples showed higher hardness and lower plastic deformation as compared with Ti-6Al-4V. The brittle behavior of the ODL samples caused the formation of cracks and the development of large acoustic signals during scratching under normal loads of 40 and 50 N. The results also showed a higher scratch and wear resistance of the ODL samples compared with Ti-6Al-4V. However, the oxygen diffusion layer formed after 3 h of oxidation showed a sharp increase in the wear rate of the alloy under a normal load of 30 N and a sliding distance of 100 m.

“…2(b). Several studies have examined TiN and TiN-based thin films deposited by conventional CVD, at different temperature levels and on several substrates such cemented carbides, tools steel, and silicon wafers [131][132][133][134][135]. Depending on the deposition parameters and on the materials involved, typical values of low temperatures CVD can go from less than 300 °C to ~700 °C [52,[134][135], while moderate-high temperatures are in the range of 800 -1600 °C [134][135][136].…”

“…In addition to its advantages, there are some disadvantages such as low wear resistance and high friction coefficient that limit the usage area [6,7]. Various heat treatments and surface coating techniques are used to eliminate these disadvantages and improve surface properties [8][9][10][11][12][13]. Studies to improve the surface properties of Ti alloys continue by using thin hard film coatings of PVD [10,11] and CVD [12,13].…”

Titanium alloys are widely used in the aerospace industry due to their good mechanical properties. Especially Ti6Al4V alloy is preferred in machine parts that require specific strength in aerospace. However, the tribological properties of the Ti6Al4V alloy are poor and need improvement. It is possible to increase the life of Ti6Al4V alloys and improve their surface properties with various heat treatment and surface coating techniques. For this purpose, in this study, plasma nitriding heat treatment was first applied to the samples prepared from Ti6Al4V alloy. Then, TiN coating was carried out by the magnetron sputtering method. Surface roughness and surface hardness were measured before and after coating. Wear tests were performed with dry friction and room temperature conditions on Ti6Al4V alloys using the sliding velocity and normal load as variable parameters. The wear track widths, the weight loss of the samples, and the abrasive disc were measured. The steady-state sliding regime average friction coefficients were determined from the recorded friction forces depending on the sliding distance. Normal load -wear track widths, normal load -friction coefficient graphics were created. Load wear track width plots showed that the wear track widths on the TiN coated and uncoated samples increased with the load. The fact that the track width values of the uncoated samples with the same load and velocity values were higher than the TiN-coated samples showed that the TiN-coated samples had higher wear resistance. In addition, it was observed that the friction coefficient values in the uncoated samples under constant sliding speed were relatively higher than the TiNcoated samples.
