摘要：
The resistance of both AISI 3161 stainless steel (AISI 3161 SS) and commercially pure titanium (cpTi) to localized corrosion in a simulated body fluid solution was investigated using numerical simulations. The resulting model, based on transport equations in dilute solutions, is designed to predict the susceptibility of these two biomaterials to crevice corrosion initiation. The results show that cpTi and AISI 3161 SS alloy are very resistant to the initiation of crevice corrosion in 0.9% NaCl solution and AISI 3161 SS alloy is more susceptible to corrosion initiation over the long term than cpTi.
