Abstract

The influences of surface nanocrystallization and gas nitriding on the antimicrobial and mechanical properties of TC4 titanium alloy was invesigated in this study. Specimens were treated with shot peening under varying parameter settings, followed by gas nitriding. XRD, SEM, and microhardness testing were used for characterization. Results show that shot peening refines surface grains to the nanoscale, forming a gradient deformation layer and significantly enhancing surface hardness. Gas nitriding of shot-peened samples produces a thicker nitride layer and higher surface hardness compared to untreated samples. However, antimicrobial tests reveal no significant improvement in bactericidal rates. The study concludes that shot peening and gas nitriding significantly enhance the mechanical properties of TC4 titanium alloy and contribute to an improvement in its antimicrobial performance.
