Effects of compressive stress on the corrosion behavior of biodegradable zinc with tension-compression asymmetry under simulated physiological environment
Biodegradable Zn vascular stents are compressed by the vessel wall while maintaining blood flow, which may lead to unpredictable deterioration of the stent due to stress corrosion. This work investigated the mechanical and corrosion behavior of Zn in a coupled environment of compressive stress and artificial plasma. The corrosion rate of Zn increases as compressive stress rises. However, the acceleration effect gradually decreased in contrast to our previous work on tensile stresses, which can be attributed to the tension-compression asymmetry of Zn-metal. Meanwhile, the corrosion mechanism of Zn was compared, and numerical models for stresses and corrosion rates were established.
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.
