“…If the presence of β-Ti increases, the wear resistant increases. Similar conclusions were reached by the authors of [12], who studied the influence of diverse heat treatments on the microstructural and tribological characteristics of Ti6Al4V ELI. No significant differences between the wear morphologies of the Ti6Al4V block surfaces were observed.…”

Structural, MechanIcal and trIbologIcal propertIeS of Spark plaSMa SIntered ti6al4V alloyThe influence of spark plasma sintering parameters on the structural, mechanical and tribological characteristics of the Ti6Al4V alloy, which is used as implant material in biomedical engineering, was investigated. The experimental data confirm that full density and attractive mechanical properties can be obtained using the spark plasma sintering method. Tribological tests, performed in dry conditions, allowed the authors to indicate the most suitable sintering parameters. The material characterized by the highest wear resistance was selected for further tribological testing in articulation with UHMWPE in simulated body fluids. Although the weight of the polymeric material articulating against the sintered Ti6Al4V was slightly higher compared to the UHMWPE articulating against the reference material (Ti6Al4V rod), the friction coefficient was lower.

The effect of heat treatment on microstructure and tensile properties as well as wear behavior on TC21 (Ti-6Al-2Sn-2Zr-3Mo-1Cr-2Nb-Si, wt.%) Ti-alloy was investigated. The samples were solution treated at 900˚C for 15 min followed by furnace cooling to 800˚C with a cooling rate 1˚C/min and holding for 20 min, then the samples cooled down to room temperature either using water quenching (WQ) or air cooling (AC). Consequently, aging treatment was applied at 575˚C for 4 hr. The microstructure feature showed a secondary α phase (α s ) precipitated in residual β phase due to the step cooling from 900˚C to 800˚C inside furnace as well as the aging treatment. The highest wear rate was obtained for WQ samples due to increasing in volume fraction of α p (58%). However, the lowest wear rate was reported for WQ + Aging samples due to the high hardness. Optimum mechanical properties of the studied TC21 Ti-alloy were obtained for AC + Aging condition. A better combination of hardness, tensile properties, and wear resistance was achieved for AC + Aging samples, although their wear resistance was found to be slightly lower than that of WQ + Aging samples.

The effect of heat treatment on microstructure and tensile properties as well as dry sliding wear behavior on TC21 (Ti-6Al-2Sn-2Zr-3Mo-1Cr-2Nb-Si, wt.%) Ti-alloy was investigated. The samples were solution treated at 900°C for 15 min followed by furnace cooling to 800°C with a cooling rate 1°C/min and holding for 20 min., then the samples cooled down to room temperature either using water quenching (WQ) or air cooling (AC). Consequently, aging treatment was applied at 575°C for 4 hr. Secondary α phase (αs) was precipitated inside the residual β phase due to step cooling from 900°C to 800°C, slow cooling rate by air cooling (AC) as well as aging treatment. The highest wear rate was obtained for WQ samples due to increasing in volume fraction of αp (58%). However, the lowest wear rate was reported for WQ +Aging samples due to the high hardness. Optimum mechanical properties of the studied TC21 Ti-alloy were obtained for AC +Aging condition. A better combination of hardness, tensile properties, and wear resistance was achieved for AC +Aging samples, although their wear resistance was found to be slightly lower than that of WQ +Aging samples.
