Surface modification using Ti-based physical vapor deposition (PVD) coatings has emerged as a promising strategy to enhance the corrosion resistance and durability of implant materials.ObjectiveThis study aimed to investigate the effect of Ti-based PVD coatings, namely TiCoCr, TiN, and TiO<sub>2</sub>, on the corrosion behavior of 316L SS under simulated physiological conditions.MethodsTiCoCr, TiN, and TiO<sub>2</sub> coatings were deposited onto 316L SS substrates using the PVD technique. The corrosion performance of the coated and uncoated samples was evaluated in phosphate-buffered saline (PBS), Hanks' solution, and Ringer's solution at 37 °C. Electrochemical corrosion parameters, including corrosion potential and corrosion current density, were analyzed to assess the effectiveness of the coatings.ResultsAll Ti-based coatings improved the corrosion resistance of 316L SS compared with the uncoated substrate. Among the investigated coatings, the TiCoCr coating deposited for 90 min exhibited the best corrosion performance. In Ringer's solution, the coating showed a corrosion potential of -0.0504 V and a corrosion current density of 4.74 × 10<sup>-6</sup> A/cm<sup>2</sup>. In Hanks' solution, the same coating demonstrated a corrosion potential of -0.1815 V and a corrosion current density of 5.0537 × 10<sup>-6</sup> A/cm<sup>2</sup>. The enhanced corrosion resistance was attributed to the protective and stable nature of the Ti-based coating layer.ConclusionThe TiCoCr, TiN, and TiO<sub>2</sub> PVD coatings significantly enhanced the corrosion resistance of 316L SS in simulated physiological environments.

Stepwise loading, microhardness testing, cartilage compression deformation measurements, and surface wettability tests were performed to systematically analyze the tribological characteristics and wear mechanisms of each material. The evaluated materials included CoCrMo, ultra-high molecular weight polyethylene, and polyether-ether-ketone (PEEK).ResultsCross-shear motion significantly increased wear in all materials. CoCrMo exhibited the largest increase (ΔK = 230.51 ± 25.67%), while PEEK showed the smallest increase in wear rate (138.37%). No significant linear correlation was found between material hardness and cross-shear wear rate (r = -0.32, p > 0.05). In terms of dynamic wettability, PEEK performed best, with a hysteresis angle 38.46% lower than that of natural cartilage, and its energy dissipation parameters were close to those of natural cartilage, indicating the best cartilage compatibility.ConclusionUnder cross-shear conditions, PEEK demonstrates the best overall wear resistance and biomechanical compatibility, suggesting its potential as a promising material for joint repair.
