Effects of Different CO2 Concentrations and Degradation Media on Static Corrosion of Commercially Pure Zinc

چکیده
Zn alloys have lately captivated the attention of scientific community as possible materials for cardiovascular applications, showing a corrosion behavior and mechanical properties in between those Mg Fe alloys. To better understand different aspects interaction with body fluids, basic pattern degradation products’ formation were investigated considering effect CO2 amount atmosphere pseudo-physiological media; that is Hanks’ balanced salt (HSS), Dulbecco’s phosphate-buffered saline (PSS) physiological solution (NSS), through 14-day static immersion study. A mixed layer mainly composed ZnO Zn3(PO4)2·4H2O Zn(CO3)2 precipitates was found on surfaces immersed both HSS PSS, independently atmosphere, while ZnO/ZnCl2 surface NSS, which also revealed higher rate due to Cl− ions. Samples tested under CO2-rich showed more compact passivating layer, dimensions crystals less cavities when HSS, PSS respectively.

Abstract: In chloride salt solutions, titanium alloys exhibit reasonably high pitting potentials as high as +10 V (vs. Ag/AgCl) at room temperatures. On the other hand, anodic pitting potentials are significantly lower in bromide solutions. In this study, pitting corrosion of commercially pure titanium in aqueous NaBr solution of 0.1 M concentration at room temperature was studied and the e...
