Dissolution and intrusion of chloride disrupted biodegradation products to persistently accelerate biodegradation of Fe-based implants
The biodegradation of Fe is severely limited due to barrier of biodegradation products. Herein, NaCl was introduced into Fe matrix and results demonstrated that NaCl significantly accelerated biodegradation rate of Fe. It was ascribed that (i) NaCl in Fe matrix initially dissolved to produce biodegradation active sites, (ii) Cl- with small ionic radii invaded the biodegradation product layer, and (iii) abundant Cl- greatly promoted the anode process of Fe biodegradation. Additionally, Fe-NaCl biocomposites also exhibited favorite cytocompatibility. These results demonstrated great potential of NaCl in accelerating the persistent biodegradation of Fe for load-bearing implants.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
