Increase in the Surface Strength of Titanium Implanted with Argon Ions

Resumo

We have studied the influence of argon-ion implantation at accelerating voltages within 40–130 kV in a dose range of (1–4) × 10¹⁶ ion/cm² on the morphology, microhardness, and fatigue strength of titanium. A method of titanium surface strengthening and modification by Ar⁺-ion implantation is proposed, which opens new possible applications of this material in electrical devices for power engineering, chemical industry, and metallurgical equipment.
