Abstract
The study aimed to analyze how milling time (2h-24h) affects structural, mechanical, and tribological properties of Ti-15Mo alloys, these last has evaluated by using XRD, SEM, and a ball-on-disk tribometer. The wear tests were carried out under applied, loads of 2, 8 and 16N respectively. Results revealed that crystallite size decreased to, 25.5nm, while lattice parameter increased to 5.34Å, and porosity reduced to 0.07%, Conversely, mean pore size decreased to 31nm after 24h. Moreover, relative density, and Young's modulus increased with prolonged milling. Coefficient of friction, wear, volume, and rate increased with applied load (2-16N) but decreased with milling time, especially in binary titanium alloys under 16N load. Optimal conditions were identified, at 24h milling and 16N load
