Enhancing the Wear Resistance of Ti6Al4V by Laser Surface Texturing

Article Preview

Abstract:

This study examines the wear behavior of Ti6Al4V following nanosecond pulse laser surface texturing (LST) using 15 W power, 60 kHz frequency, and 180 mm/s speed. Tested under dry sliding conditions with a 20 N load, 0.3 m/s speed, and 900 s duration, LST produced melt bulges that enhanced surface wear resistance. This study demonstrates that nanosecond pulse laser surface texturing on Ti6Al4V significantly enhances wear resistance, reducing wear rate by 3% and coefficient of friction by 5%.
