The Ti-6Al-4V alloy is widely used in orthopedic and dental implants due to its excellent mechanical, corrosion, biological properties. However, it exhibits several limitations that can compromise performance clinical applications. Notably, the suffers from a high coefficient of friction, which lead increased wear reduced longevity under relative movement conditions. Additionally, shows susceptibility localized corrosion physiological environments, particularly presence bodily fluids may result formation pitting. These challenges underscore need for surface modifications enhance alloy’s tribological performance, thereby improving overall efficacy durability as biomaterial medical settings. In this context, manuscript presents applied innovative research assesses impact implementing nanostructured Nb2O5 coatings through reactive sputtering technique on both air artificial saliva (AS) solution conditions using Pin-on-Disk apparatus. coating demonstrated ability reduce rate volume by up 88% without inducing any Ra Rt Ti-6Al-4V, feature desirable applications implantable devices. reduction be attributed shift adhesive mechanisms uncoated surfaces abrasive coated surfaces. This highlights strategic advantage utilizing Brazil’s abundant niobium resources advance technology facilitate benefit public health.
