In this study, the wear behavior of a physical vapor deposition (PVD) AlTiN coated on the titanium alloy was investigated. Response surface methodology (RSM) was used to analyze input factors, such as load (A), sliding speed (B), and sliding distance (C), while wear mass loss (WML) and coefficient of driction (COF) were considered as the response parameters. The statistical analysis shows that main factors, that is, interaction of AC and pure quadratic terms B2 and C2, have maximum influences on WML. However, COF was highly affected by load, sliding speed, and interaction of AB and quadratic term A2. The present work attempts to carry out empirical modeling to predict output response on WML and COF. Desirability-based optimization technique was employed to obtain minimum WML and COF. Microscopy images of the wear tracks reveal visible grooves and scratches that confirm abrasive wear to be the primary wear mechanism accompanied by adhesive wear. The investigation concluded that AlTiN has better wear resistance properties and can be used to coat titanium implants for biomedical application. The result shows that the minimum WML and COF have been found at applied load 15 N, sliding speed at 0.5 m/s, and sliding distance 500 m.

“…e alloy Ti-6Al-4V is widely acceptable and viable for structural applications in aerospace or aviation vehicles. PVD coatings have been shown to improve mechanical properties, biocompatibility, osseointegration, wear, and corrosion resistance in Ti-6Al-4V and SS 316 LVM substrates [12,13]. Out of all titanium alloys, Ti-6Al-4V is the most preferable to use in engine components, airframe, and aerospace components.…”

The effect of thermal cycling on tensile properties and microstructural characterization of Titanium (Ti–6Al–4V) alloy which were subjected to various types of thermomechanical treatments especially stress relief annealing and solution treated aging were studied and results presented. The specimens were thermally treated at a temperature of 427°C for up to 1500 cycles. The test setup used for thermal treatment of the specimens was a specially designed experimental setup. After thermal treatment the specimens, were prepared for a tensile test to get the desired tensile properties. It was noticed that the maximum tensile strength of the specimen was observed when reached at 250 cycles and thereafter marginally increasing up to 1000 cycles. After 1000 cycles the tensile strength of the specimen decreases. Similarly, the hardness of the specimen increases up to 1000 cycles and then decreases after 1000 cycles, while elongation increases marginally when the cycle increases. Solution-treated aged specimen attains greater strength and hardness when compared to stress relief annealed specimen. With the increased number of cycles, the strength of the specimen when treated with stress relief annealing and solution-treated aging specimen increases. It was observed that the hardness and strength values decrease after 1000 cycles. With an increasing number of cycles, the tensile elongation increased. When compared with both the treatment processes the solution-treated aged specimen shows better results after thermal cycling.
