Novel Hierarchical Micro/Nano Modified Surfaces for Dental Implants
Journal Title: Acta Marisiensis. Seria Technologica - Year 2018, Vol 15, Issue 1
Abstract
Present paper presents the modification at nano scale level of the surfaces of Ti6Al4V alloy that were previously modified at micro scale level by acid etching (AE) or by sand blasting with large grit and acid etching (SLA). Continuous, self-ordered nanostructured (nanoporous/nanotubular) oxide layers superimposed onto micro rough topographies were developed by using electrochemical anodization in fluoride based solutions, and optimized process parameters. Novel hierarchical micro/nano modified surfaces, with well developed oxide nanotubes of 40-110 nm in diameter, were synthesis by anodization in 1M H3PO4 + 0.4 wt% HF electrolyte, at anodization potential of 24 V, applied with a potential ramp of 0.08 V/s.
