Abstract
The in vitro corrosion of Fe-30Mn-1C in a Ca-modified Hanks’ balanced salt solution was investigated for biodegradable cardiovascular stents with a rotating disc electrode. A blood flow-related approach was developed to adjust laminar flow conditions. Electrochemical monitoring revealed that intermediate flow caused maximum corrosion, while static and high flow conditions led to minimal corrosion. Surface analysis indicated the formation of a non-crystalline, nanoscopic degradation layer, whereby thickness, porosity and layer-disrupting defects are strongly affected by flow conditions. The interplay between laminar flow and the degradation layer was crucial for the steel degradation and discussed by employing a hydrodynamics-based corrosion scheme.
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.
