Basics of biodegradation of iron scaffold
The physicochemical properties of iron and its possible corrosion products in different solutions are listed in Table 2.5.1. The possible corrosion products of iron in water or NaCl solution include corresponding hydroxides and oxides and their intermediate products [1-5]. The corrosion products also include some phosphates of iron in phosphate solution . Only Fe3O4 is magnetic in all corrosion products. The volume of solid substances will increase gradually during the corrosion process of iron. Based on their density data in Table 2.5.1, the volume will increases to 1.5 times when Fe changes to Fe2O3, and 2.35 times when Fe changes to Fe(OH)3. Actually, it is possible that the volume increases to 3-8 times due to the fact that the corrosion products are loose.
