Corrosion resistance of iron‐containing experimental titanium alloys exposed to simulated body fluids

In this study, experimental Ti–6Al–1V–3Fe, Ti–4.5Al–1V–3Fe, and Ti–3Fe alloys, as well commercial Ti–6Al–4V alloy that were scaled up utilizing vacuum induction melting technology, assessed for corrosion performance in simulated body fluids. The selected fluids 0.9 wt% NaCl solution Hanks balanced salt (HBSS). Open circuit potential linear polarization scans performed to understand the of alloys. surface alloys was examined before after exposure corrosive solutions using scanning electron microscopy. results show all exhibit good rates less than 0.5 mm/year. Owing higher lower rate, Ti–6Al–1V–3Fe Ti–4.5Al–1V–3Fe had best resistance HBSS, respectively. All consist a fully lamellar structure with α β phases. There no evidence severe deterioration on exposed
