Metallic Corrosion

Fundamental Aspects of Corrosion of Metallic Materials

A corrosion model for bioabsorbable metallic stents.

In this study a numerical model is developed to predict the effects of corrosion on the mechanical integrity of bioabsorbable metallic stents. To calibrate the model, the effects of corrosion on the integrity of biodegradable metallic foils are assessed experimentally. In addition, the effects of mechanical loading on the corrosion behaviour of the foil samples are determined. A phenomenologica...

Control of metallic corrosion through microbiological route.

Involvement of biofilm or microorganisms in corrosion processes is widely acknowledged. Although majority of the studies on microbiologically induced corrosion (MIC) have concentrated on aerobic/anaerobic bacteria. There are numerous aerobic bacteria, which could hinder the corrosion process. The microbiologically produced exopolymers provide the structural frame work for the biofilm. These pol...

Metallic plate corrosion and uptake of corrosion products by nafion in polymer electrolyte membrane fuel cells.

Nafion contamination by ferrous-alloy corrosion products, resulting in dramatic drops of the Ohmic potential, is a suspected major failure mode of polymer electrolyte membrane fuel cells that make use of metallic bipolar plates. This study demonstrates the potential of scanning transmission X-ray microscopy combined with X-ray absorption and fluorescence microspectroscopy for exploring corrosio...

Metallic Medical Implants: Electrochemical Characterization of Corrosion Processes

whole range of medical implants is justified by their superior mechanical properties (hardness, stiffness, etc.) compared, for example, to polymers. Other properties like biocompatibility or visibility in X-ray images also can be mentioned. One of their drawbacks is that electrochemical reactions take place on metallic surfaces in the human body. To replicate the real environment as closely as ...
