Corrosion Behavior of a New Ti–3Mo Alloy in Simulated Body Fluid for Biomedical Applications

Magnesium (Mg) alloy possess a high demand in biomedical applications due to their biocompatibility and biodegradability. However the main limitation for Mg alloy is their fast degradation rates in physiological environment. This paper reports the preparation of porous Mg alloy through powder metallurgy technique by using ammonium bicarbonate (NH4HCO3) as space holder material and hexane as solvent. The corrosion behavior and degradation rate of porous Mg alloy was measured after 24h, 96h and 168h respectively of immersion in simulated body fluid (SBF) with compact Mg alloy as control. The results reported that degradation rate increased with increasing immersion period, yet the compact Mg alloy shows better degradation rate than porous Mg alloy. Moreover, the pH of SBF changed proportional to immersion period and stabilized after 96h of immersion.

Titanium alloys and stainless steel 316L are still the most widely used biomaterials for implants despite emerging new materials for this application. There is still someambiguity in corrosion behavior of metals in simulated body fluid (SBF). This paper aims at investigating the corrosion behavior of commercially pure titanium (CP-Ti), Ti–6Al–4V and 316LVM stainless steel (316LVM) in SBF (Hank’s solution) at37 ºC using the cyclic polarization test. Corrosion behavior was described in terms of breakdown potential, the potential and rate ofcorrosion, localized corrosion resistance, andbreakdown repassivation. The effects of anodizing on CP-Ti samples and the passivation on the 316LVM were studied in detail. It was shown that CP-Ti exhibited superior corrosion properties compared to Ti–6Al–4V and 316LVM.
