Electrochemical Corrosion of Magnesium Alloy for Cardiac Implants in Artificial Plasma Solution

Abstract:

The study presents results of electrochemical corrosion tests of extruded magnesium alloy WE43 used for stents in cardiology. Corrosion tests were performed in artificial plasma with application of the system for electrochemical tests VoltaLab PGP201. Potentiodynamic tests enabled to register polarisation curves. Scanning microscope were used for assessment of the surface of tested alloy after corrosion tests. It was proved that the alloy is susceptible to pitting corrosion. Options of magnesium alloy WE43 application in cardiology are connected with the need for application of protective layers on implants made of the tested alloy.
