Abstract
Objective: The development of newer archwires can be achieved either by discovering novel materials or by modifying existing ones. The objective of the present study was to coat beta-titanium (β-Ti) archwires with tetrahedral amorphous carbon (ta-C)/hard carbon and to evaluate selected physical and mechanical properties. Methods: Hard carbon–coated (n = 5) and uncoated (n = 5) β-Ti wires were assessed for surface roughness, wear resistance, load-deflection characteristics, and friction using appropriate testing apparatus under dry in vitro conditions. Results: Compared to uncoated β-Ti wires, ta-C–coated β-Ti wires demonstrated a statistically significant reduction in surface roughness, increased wear resistance, and lower coefficients of friction (p < 0.05). However, the ta-C coating did not significantly affect load-deflection properties. Conclusion: Hard carbon (ta-C) coating enhances the surface and tribological properties of beta-titanium archwires without altering their mechanical behavior. Within the limitations of this in vitro study, ta-C–coated β-Ti wires are superior to uncoated β-Ti wires.
