“…Various strategies are used to improve the wear resistance of titanium alloys and permit their efficient usage as a sliding material. Heat treatment, composition adjustment surface modification, and matrix reinforcement with precipitates are different mechanisms for improving the wear resistance of materials [23].…”

The transition from mild to severe wear mechanism of Ti-6Al4V alloy was investigated. Microstructure and wear micromechanisms were also investigated. The as-cast samples were subjected to hot swaging at 900°C, followed by two separate solution treatments on the swaged samples. The first treatment was applied at a temperature of 850 °C (below the β-transus temperature) for getting a bimodal structure (α+β), while the second treatment was performed at 1050 °C (above the β-transus) for getting a lamellar structure (β). The solution-treated lamellar structure resulted in an ultimate strength of 1335 MPa and a hardness of 440 HV20 which are significantly superior to the bimodal structure. The wear behavior of the studied Ti64 alloy was investigated at different sliding speeds in the range of 0.5 to 2.5 m/s with 0.5 m/s interval. The transition from mild to severe wear mechanism was obtained at 1.5 m/s. The lowest wear rate was reported for the samples solution treated at 1050 °C due to their fine lamellae (α+β) structure and the high hardness. SEM was used to evaluate the worn surfaces of some samples to determine the wear micro-mechanisms.

“…Those are surface modification, composition adjustment, heat treatment, reinforcing the matrix with some precipitates, etc. [23]. In the present study, there is a trial to improve the tribological behavior of the titanium alloy under investigation by applying solution treatment either above or below the beta transus that followed by ageing at 500 °C for 18 hrs.…”

The mild to severe wear transition of Ti-6Al-4V titanium alloy was investigated. The correlation between microstructure and wear micro-mechanisms was also studied. Hot swaging at 900 °C was performed on the as-cast samples and thereafter two different solution treatments were applied on the swaged samples. The first treatment was applied at a temperature of 850 °C (below the β-transus temperature) for getting a bimodal structure (α+β), while the second treatment at 1050 °C was applied (above the β-transus) for getting lamellar structure (β). The solution treated lamellar structure resulted in ultimate strength of 1335 MPa and a hardness of 440 HV20 which are significantly superior to the bimodal structure. Wear behaviour of the studied Ti64 alloy was investigated at different sliding speeds in the range of 0.5 to 2.5 m/s with an interval of 0.5 m/s. The mild to severe wear transition was obtained at 1.5 m/s. The lowest wear rate was reported for the samples solution treated at 1050 °C due to their fine lamellae structure with high hardness. The worn surfaces of some selected samples were examined using SEM to determine the wear micro-mechanisms.
